Chugunov, A. Nechaev] A comparative study is made of the properties of six types of carboxyl cationites differing by the composition and structure of the matrix. It is shown that the use of weakly acidic ionites as the charge in the upstream filters in the special water purification system and block desalination setups will make it possible to extract very efficiently the lithium, potassium, ammonium or monoethanolamine ballast salts from the purified flows with dealkalization of the flows. As a result, the effective capacity of the regular filters can be increased considerably and, correspondingly, their service life extended by decreasing the volume and salt content of the secondary liquid radioactive wastes.
