Currently in Russia ion exchange processes with various sorption media types are widely used for decontamination of liquid radioactive waste (LRW) from strontium radionuclides. However in most cases for decontamination of LRW with high hardness salt content the above mentioned sorbents are inefficient, which is associated with low selectivity of those with respect to strontium. One of the most effective sorbents for decontaminating LRW from strontium radionuclides is the manganese (III, IV) hydroxide based inorganic sorbent possessing higher selectivity to strontium ions. It is worth to mention that until recently an industrial-scale technology for producing batches of the manganese (III, IV) hydroxide based inorganic sorbent with predetermined operational and sorption-selective properties was not available. In our paper the technological principles for synthesizing industrial-scale manganese (III, IV) hydroxide based sorbent batches are reported. Data on the main operational and sorption-selective characteristics of the sorbent as well as the results of LRW decontamination from strontium radionuclides at different objects are given and discussed.
