AbstractThe work is devoted to the research of selected operational properties of the sorbing matrix material laboratory samples for the immobilization of radionuclides on the basis of local zeolite-containing rocks. It is shown that zeolite-containing rocks are sufficiently thermally stable for use as a raw material for producing of the sorbent matrix material for immobilizing radionuclides. The stages of processing zeolite-containing rocks for the purpose of sorbing matrix material obtaining for the immobilization of radionuclides are given. Optimum parameters of ultrasonic processing of raw materials are found. It is shown that the initial particle size of zeolite-containing rocks practically does not influence the values of the main operational properties of the produced sorbing matrix material for the immobilization of radionuclides.
Keywordszeolite-bearing rocks, radionuclides, cesium leaching rate, total sorption capacity, thermal stability, ultrasound, steaming
