Essay

The thesis comprises results of the research aimed at determination of efficiency and development of methods for decontamination of water containing 137Cs and 90Sr radioisotopes by means of application of coagulants, sorbents, ion-exchange resins, flocculants. On the basis of the obtained results, there have been developed new technologies of decontamination of low-activity sewage, contaminated with 137Cs and 90Sr radioisotopes, by using ferro-cyanide-polyammonium complexes, ensuring decrease in activity and chemical oxygen demand down to allowable levels, multiple reduction in radioactive waste volume. The results of researches had been introduced into production.
