Comparative analysis of the method of natural radioactively-contaminated waters and model liquid radioactive waste containing B-Trilon, ammonium acetate, and NaNO3 with natural and artificial nonorganic sorbents (aluminum silicates, ferrocyanide sorbents based on hydrated titanium dioxide, klinoptyalolith, glauconit, Termoxid-3A and Termoxid-35 sorbents) was carried out. It was demonstrated that when treating low-saline solutions and drinking water in respect of cesium radio nuclides the highest distribution ration 1.0·107 ml/g was observed for NKF- klinoptyalolith sorbent. When decontaminate solutions containing B-Trilon the cesium distribution ratios with artificial sorbents Т-35, NKF- hydrated titanium dioxide and natural aluminum silicates (klinoptyalolith and glauconit) were comparable and equal, depending on the B-Trilon concentration ~102‒103 ml/g. To treat high-saline NaNO3 solutions NKF- hydrated titanium dioxide and NKF- glauconit were effective: cesium distribution ratios from NaNO3 solution with 2 mol/l concentration were 6.1·104 and 1.7 ·104 ml/g, respectively.
