CROSS-LINKED SULFUR-CONTAINING COPOLYMER AS A SORBENT OF TRANSITION METAL IONS AND A METHOD OF ITS PREPARATION

摘要

Application: synthesis of new sulfur- containing sorbents with high sorption capacity for translational ions of copper, cobalt, nickel. SUMMARY OF THE INVENTION: s a copolymer of formulas -CH2 () n-; (CH- (CO2H) m - (- CH2-CH- (Ci4Hi2S04) CH- CH-) K, where n 68,65-70,11; 26,94-28,25 m; k 2,95-3, .. 09 mol% sorbent is prepared by copolymerizing styrene, acrylic acid and the diallyl ether dioksidife- nilsulfona at a molar ratio of di-allyl ester: dioksidifenilsulfon: acrylic acid: styrene = 1: 8,7- 9.58: 22,22-23, 77, in the presence of benzoyl peroxide in an inert environment. sorbing copper ions in an amount of 352, 447 of cobalt, nickel, 256 mg / g. s.p.f 2-ly.
