USE OF CHEMICAL PRECIPITATION PROCESSES IN PRACTICE OF LIQUID RADIOACTIVE WASTE TREATMENT

摘要

In this work information is presented on the installation, which is developing for treatment of liquid radioactive waste. The characteristics of liquid waste generated during decontamination of industrial facilities in Republic of Belarus are also presented. The results of treatment of simulated liquid waste for 137{sup left}Cs removal using method of chemical coprecepitation at different ratios of sedimenting reagents are described. The received data are juxtaposed with the results of sedimentation kinetic of nickel ferrocyanide at the same conditions. The last-named data were obtained by the methods of optic spectrophotometry and radioactive tracers. Methodology of synthesis and properties of cation-exchange fiber FTBAN K-1 modified by cobalt ferrocyanide is described. This sorbent has high sorption ability towards 137{sup left}Cs and may be used at the liquid waste treatment facility.
