Использование: изобретение относится к способам очистки жидких радиоактивных отходов (ЖРО) от ионов цезия-137. Может быть использовано в области радиохимии, ядерной технологии, атомной энергетике и др. Цель: повышение очистки сточных вод от радионуклидов, упрощение процесса очистки ЖРО от ионов цезия-137. Сущность изобретения: ЖРО, содержащие в своем составе цезий-137, пропускают через слой сорбента, представляющий ферроцианиды никеля, иммобилизованные в матрицу волокон нитрон, облученных гамма-квантами с экспозиционной дозой 2,58.103 - 2,58.104 кЛ/кг, процесс сорбции осуществляют при pH ЖРО 8,5 - 9,7. Положительный эффект: процесс сорбции одностадийный, непродолжительный, достигается высокая степень сорбции, 99 - 99,5%.Usage: the invention relates to methods for purifying liquid radioactive waste (LRW) from cesium-137 ions. It can be used in the field of radiochemistry, nuclear technology, nuclear energy, and others. Purpose: to increase wastewater treatment of radionuclides, to simplify the process of cleaning LRW from cesium-137 ions. The essence of the invention: LRW containing cesium-137 is passed through a sorbent layer representing nickel ferrocyanides immobilized in a matrix of nitron fibers irradiated with gamma rays with an exposure dose of 2.58.10 3 - 2.58.10 4 kL / kg, sorption carried out at a pH of LRW 8.5 to 9.7. Positive effect: the sorption process is one-step, short-lived, a high degree of sorption is achieved, 99 - 99.5%.
