摘要：

A cation exchanger with an exchange capacity of 4.85 meq/g and mechanical strength of 96% was obtained by sulfonation of a styrene copolymer grafted to petroleum asphaltite. It can be used for sorption of ions at temperatures up to 100°C and radiation doses of up to 6.7106 Gy. The adsorbents made from this type of raw material are characterized by a developed micropore structure.
