【 摘 要 】

Porous resorcinol-formaldehyde resins were fabricated by leaching an inorganic filler introduced earlier into the polymer and by polymerization of the emulsion dispersed medium. The sorption properties of the fabricated materials with respect to the micro-quantities of 137Cs were investigated under dynamic conditions at high feeding rates of a model highly mineralized alkaline solution. It has been shown that the fabricated ion exchangers are characterized with high decontamination factors in comparison with the initial nonporous resin.
