Treatment of Radioactive Liquid Wastes by Ion Exchange (in Japanese)
The treatment of radioactive liquid wastes hy ion exchange has been widely adopted, alone or combined with other processes. Among various ion exchangers, inorganics are more economical than organics if no regeneration is practiced in the process. Coprecipitation and pH control may be added to the process with cation exchangers, allowing selectivity of specific nuclides. Desalting systems in combination cat ion and anion exchangers give higher decontamination factors, while the ion exchange membrane treats highly concentrated wastes more econominally. In general, low level wastes can be treated with cheaper cation exchangers only, by the coprecipitation method. The decrease of exchange capacity by strong radicactivity is especially noticeable on anion resins. Studies were made of the removal of radioactivity from wastes by soils or soil forming minerals. By utilizing soils, the wastes may be disposed directly to the ground. The past history, the present status, and the future prospect of waste treatment by ion exchange are reviewed, summarized, and discussed in six categories,
