The purpose of this work is to investigate the sorption of Cu2+, Co2+, Ni2+, UO22+ ions, etc. depending on the ionic form of the cationite and the pH of the medium on phosphoric acid cationite obtained by forsforylation of a polymer based on cubic waste of the Shurtan gas-chemical complex and a secondary product of the hydrolysis industry – furfural. It was found that copper and UO22+ ions are best sorbed by cationite when the cationite is in Na form. The UO22+ ion is sorbed fairly well in the range of pH =2.5-11 when UO22+ is in Na form. The best desorbent of absorbed copper, Ni, Co ions is sulfuric acid, and for the UO22+ ion – NaHCO3. The study of the sorption mechanism of the studied ions showed that Na, Ca – ions are extinguished due to pure ion exchange, copper and Ni ions due to ion exchange and partially due to complexation, whereas UO22+ ions, only due to complexation.
