Innovative remediation strategy for toxic mercury species in the area of former Pavlodar chemical plant

Inovatívna stratégia sanácie toxických druhov ortuti v areáli bývalého chemického závodu Pavlodar

Duration: 15. 4. 2022 - 1. 11. 2024
Evidence number:AP13067724
Program: Iné
Project leader: RNDr. Baláž Matej PhD.
Annotation:The project is expected to develop an innovative strategy for remediation of the area of the former Pavlodar (Kazakhstan) chemical plant from mercury toxic forms using data on occurrence of mercury species (including methylmercury, mobile and bioavailable forms). These forms, determined by modern physicochemical and analytical methods, will help to assess the Hg mobility, toxicity and the ability to methylation at this location and will make it possible to propose a rational approach to remediate the territory. In addition, it is planning within the project to develop and offer for commercial use at least one material/product as an in situ amendments to stabilize/immobilize mercury in soils and/or to remove it from water.

POTASSIAL - Zero-waste valorisation of feldspathic ores: Green application and sustainable sourcing of strategic raw materials.

Bezodpadové zhodnotenie živcových surovín: Zelené aplikácie a udržateľné získavanie strategických nerastných surovín.

Duration: 15. 4. 2022 - 14. 4. 2025
Evidence number:JTC-2021_027-POTASSIAL
Program: ERANET
Project leader: Mgr. Achimovičová Marcela PhD.
Annotation:Feldspathic ores containing mainly K-Feldspar (KAlSi3O8) will be valorised by applying several hydro- and pyrometallurgical processes at which KCl, Al2O3, and SiO2 will primarily be produced without generating any solid waste. Objective is to provide new resources for potash and alumina. Targets are to produce fertilizer-grade KCl, high purity Al2O3, synthetic SiO2, Ca-silicate, and SiC from one ore and to sequester CO2 on the same ore. Although there are many studies for K and Al2O3 recovery from feldspars and clays, there are no notable commercial attempt to date. Unlike the other KCl and Al2O3 production methods suggested in the literature, manufacturing KCl, Al2O3, SiO2, Ca-silicate and SiC from the same ore without generating any waste is the novelty of this project. Thus, innovative aspect of the project is that feldspathic ores will be processed as a source of high value-added materials for the first time and with zero-waste approach, thus increasing the economic value of the proposed process. Also, CO2 sequestration capability of the feldsphatic ores will also be verified to enhance the economic importance those types of resources. For increased raw materials efficiency, a novel, hybrid and zero-waste processing method will be put forward. This will be established by exploiting the ores, other than bauxite and natural potash ores, and by applying environmentally sensitive production processes. The project will unlock substantial volume of various raw materials from deposits that cannot be economically or environmentally exploited within or outside the EU through enabling the better efficiency of exploitation of raw materials’ resources and increasing the range and yields of recovered raw materials; and push Europe to the forefront in the area of raw materials processing technologies and increase availability of recovered raw material and create added value products through reducing the amounts of industrial tailings to be disposed or landfilled.

Duration: 1. 1. 2023 - 31. 12. 2024
Evidence number:BAS-SAS-2022-06
Program: Mobility
Project leader: RNDr. Fabián Martin PhD.
Annotation:The project aims to enrich and refine the knowledge about the type, role and significance of various factors determining the structure and properties of supported bimetallic Co-Pd catalysts for CO hydrogenation like supported metal(s) dispersion, degree of metal reduction, surface structure of metal particles, extent of the metal phase components influence on the type and properties of adsorbed atoms and compounds, role of support composition and surface properties. Enrichment and clearance of details of the catalytic CO hydrogenation mechanism could be obtained. The main hypotheses for the study are: - The selectivity and distribution of reaction products is determined by the reduction and dispersion of the metal, as it is established that the main active phase are metallic nanoparticles where essential part of their surface consists of totally reduced cobalt atoms (Co0 ) but some results show necessity of Co0 /Con+ couples. - The type of CO adsorption, formation of various CO species will depend on the surface composition of the studied material - namely the presence/ratio of metal ions and atoms of the catalytically active components. - Mechanochemical synthesis of catalysts for CO hydrogenation could be profitable for simultaneous desirable modification of support surface properties

CLEANWATER - Multifunctional sustainable adsorbents for water treatment assisted with plasma technologies and for health protection from xenobiotics

Multifunkčné udržateľné adsorbenty na úpravu vody pomocou plazmových technológií a na ochranu zdravia pred xenobiotikami

Duration: 1. 1. 2024 - 31. 12. 2027
Evidence number:101131382
Program: Horizont Európa
Project leader: Melnyk Inna PhD.
Annotation:Contamination of drinking-water is an urgent global health concern, preferentially in rural areas, and is highly related to the poor and vulnerable population. This challenge requires a single, easy to handle and low-cost solution able to decrease the levels of pathogens, chemical and radiological hazards to tolerable levels in a single and simple pot (from a sorbent on a glass to a more powerful cold plasma technology). Furthermore, climate change, natural disasters and the actual war in Ukraine urges having available fast effective solutions to avoid the spread of waterborne epidemies and being exposed to unsafe levels of heavy metals or hazardous organic pollutants. The complexity of such contamination including organic/inorganic species, cationic/anionic species, different size and shape, etc., requires a multicomponent system and/or device, in the form of a tablet or monolith, able to tackle specifically each of these hazards at once. In addition, this multicomponent system, besides tacking the problem in water, can be prepared and/or modified to be biocompatible so that it can also be used as a dietary complement to mitigate/remove all these hazards in human body (as enterosorbent). Based on these premises, the main goal of the CLEANWATER project is the design and development of multicomponent sorbents prepared by the combination of safe materials (e.g., activated carbons, bone-chars, pectins, among others) able to eliminate these contaminants in drinking water in a single pot or in combination with cold plasma for complete destruction. Furthermore, this sorbent will be modified accordingly to be applied in human body as a dietary complement to remove these species once assimilated in the body.

Project leader: RNDr. Baláž Matej PhD.
Annotation:High-energy milling is a mineral processing technique initially developed for the treatment of raw materials during mining activities. In the proposed project, it will be used to treat calcite mineral present in the eggshell waste in order to improve its adsorption capability against selected heavy metal ions and dyes from both model solutions and real wastewaters from the mining regions. Additionally, bio-based calcite and the organic residue will be used as active reactants in the synthesis to yield nanocrystalline minerals (sulfides, oxides and their composites) and as a catalyst for the selected organic reactions. Both adsorption and nanomaterials synthesis will be also performed with selected common plants as natural raw materials. Eggshell and selected plants will be also applied as reducing agents to yield Ag and AgCl nanoparticles. The application of the obtained products in the fields of photocatalysis, thermoelectrics and in biomedicine will be tested in collaboration with foreign partners.

Evidence number:2/0116/23
Program: VEGA
Project leader: RNDr. Zubrik Anton PhD.
Annotation:The project is focused on the preparation of advanced carbon adsorbents from local precursors (e.g. Slovak lignite, waste biomass). Microwave heating will be applied in the pyrolytic synthesis of the adsorbents, their surface activation, and modification, as well as in the regeneration process. The modification will be realized by incorporating magnetic nanoparticles (Fe (0), Fe-oxides) into carbon structures. It allows the separation of the solid adsorbent from the cleaned water by magnetic filtration. In addition to the static adsorption experiments, the dynamic mode will be applied during the adsorption studies to eliminate selected toxic metals/metalloids and organic pollutants. Desorption and regeneration of adsorbents as well as microwave degradation of organic pollutants will also be examined. The main goal is to prepare the advanced material with excellent surface properties applicable in the environmental technologies e.g. for remediation of mine drainage and industrial wastes.

AUHR - Gold recovery from White Hill (Detva) concentrate using algae and mechanical activation

Získavanie zlata z koncentrátu Biely vrch (Detva) s využitím rias a mechanickej aktivácie

Duration: 1. 1. 2023 - 31. 12. 2025
Evidence number:2/0084/23
Program: VEGA
Project leader: Ing. Ficeriová Jana PhD.
Annotation:Complicated technological treatment of gold-containing concentrates and non-ecological methods of their processing have initiated the use of a non-traditional environmental method of this precious metal recovery. For these reasons, the scientific project is focused on gold obtained from concentrate White Hill (Detva) by using algae and mechanical activation. Mechanical activation of the concentrate and silica shells of freshwater algae causes changes in the physico-chemical properties of gold carriers as well as mineral components of algae. These structural changes have a decisive influence on the precipitation of nano-size gold into solutions of environmentally friendly reagents, from which the gold is subsequently fixed in the cell matrix on mechanically activated silica algae shells. The gold nanoparticles obtained in this way can have a very important benefit in practice for the disposal of hazardous substances in the environment.
