 The result of the work was: - an informational search for sorbents that can be used for vitrification of radioactive waste and determination of the properties of sorbents and an informational search for the effect of plasma on plastic micro- and nanoparticle was carried out. - the purification of RRV from surface-active substances and organic compounds by oxidation-cavitation and electro-hydrodischarge methods was investigated; - developed a method for cleaning aqueous solutions from nanoplastics using colloid of iron hydroxide and bentonite clay, which ensures the separation of nanoplastics from the dispersion medium, and conducted experimental work on the effect of plasma on the oxidation of nanoplastics. - prepared laboratory samples of sorbents based on nickel ferrocyanide of potassium and bentonite clay, intended for the removal of radionuclides from RRV, and a sample based on iron hydroxide nanoparticles of bentonite clay for compaction in the composition of hyoscement. - a complex plasma-chemical method of cleaning polluted waters from micro- and nanoplastics was developed, which involves plasma-chemical treatment of a liquid contaminated with micro- and nanoplastics, to which an aqueous dispersion of highly dispersed smectites modified by humates is previously added, which ultimately leads to the formation of magnetically sensitive aggregates with the inclusion of micro- and nanoplastics , which are removed by magnetic separation. - 2 scientific articles, 1 theses were published and 1 application for a useful model was issued
