Abstract
The comparison assessment of the efficiency of sorption purification of low-level active liquid radioactive wastes by polyfunctional materials based of layered double hydroxides and hexacyanoferrates of metals is carried out. The values of the distribution coefficients of radionuclides on these sorbents reach 103–105 cm3/g and are comparable with obtained world analogues. It was established that heat treatment of waste materials (600–800°C) provides reliable isolation of ecotoxicants.
