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.

多功能材料—用于净化液态放射性废物的有效吸收剂

进行了基于层状双金属氢氧化物和六氰合铁酸盐的多官能材料对低水平活性液态放射性废物的吸附净化效率的比较评估。放射性核素在这些吸附剂上的分布系数值达到10 ³ –10 ⁵ cm ³ / g，与获得的世界类似物相当。已经确定，对废料进行热处理（600–800°C）可以可靠地隔离生态毒物。
