Project budget: 6.000 EUR
The aim of this project is synthesis of structurally stable hybrid nanomaterials based on surface-modified magnetite with humic substances. The accent is on nanomaterials that must have high efficiency and adsorption capacity of radiotoxic elements from contaminated water, while their magnetic nature provides their efficient and inexpensive separation external magnets after the remediation process. The humic substances and additionally functionalized humic acid will be used for coating (modification) of the magnetite surface (Fe3O4/HA and Fe3O4/HAf). It is planned to use magnetism of formed hybrid structure in a fast and efficient separation of materials help of powerful Nd-Fe-B magnets. Three radionuclides (Cs, Sr and Co) are tested in various aqueous matrices (deionized water, groundwater, river and sea water) as a model system for remediation of contaminated water.
