Представлены результаты исследования сорбции радионуклидов цезия, стронция и кобальта перспективными сорбентами на основе термически модифицированных горючих сланцев из растворов, моделирующих жидкие радиоактивные отходы. На основании результатов низкотемпературной адсорбции–десорбции азота установлена зависимость текстурных параметров исследуемых сорбентов от метода обработки горючего сланца, а также описана зависимость эффективности сорбции (по величинам сорбции и коэффициента распределения) радионуклидов от текстурных параметров сорбентов. Понимание того, каким образом характеристики пор оказывают влияние на сорбционную активность таких сложных систем, как сорбенты, важно для создания высокоэффективных сорбционных материалов с усовершенствованными характеристиками. Установлено, что материалы на основе модифицированного горючего сланца сорбируют радионуклиды цезия, стронция, кобальта с высокой эффективностью: коэффициенты распределения каждого радионуклида составляют 103–104 мл/г при степени извлечения более 66 %. Наибольшую эффективность проявляет сорбент, полученный из горючего сланца при нагреве со скоростью 5 град/ мин без последующей обработки паром. Данный сорбент рекомендован к применению для очистки жидких радиоактивных отходов низкой активности от радионуклидов цезия, стронция, кобальта.

The results of the study of cesium, strontium, cobalt radionuclides sorption from model solutions simulating liquid radioactive waste on promising sorbents based on thermally modified oil shale are presented. The dependency of texture parameters obtained from the results of nitrogen adsorption-desorption on the treatment method of oil shale and their relationship to sorption parameters such as distribution coefficient and removal efficiency was discussed. Understanding how pore characteristics affect the sorption activity of such complex systems as sorbents is important for the creation of radionuclide sorption materials with improved characteristics. The efficiency of sorption of cesium, strontium and cobalt radionuclides was rather high for sorbent samples: the distribution coefficient was about 103–104 ml/g with a removal efficiency of more than 66 %. The most effective sorbent was obtained from oil shale with a heating rate of 5 deg/min without subsequent steam treatment, which is recommended to be used for low-active radioactive waste treatment.
