▎ 摘  要

NOVELTY - Ion exchange resin is prepared by performing phosphonylation reaction on graphene composite copolymerization white ball and a condensing agent at 80-200degrees Celsius, performing acidification and hydrolysis reaction on a cooled phosphonylated product and acid at 50-180degrees Celsius, cooling to room temperature after the reaction is finished, and performing post-treatment. USE - Ion exchange resin that is used for processing petrochemical wastewater (claimed). ADVANTAGE - The method greatly improves processing performance and conductivity, the exchange capacity is larger than that of the conventional strong acid resin, and improves the electrical regeneration performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing an ion exchange resin for petrochemical wastewater treatment, which involves: (a)subjecting ion exchange resin to a phosphonylation reaction at 80-200degrees Celsius through graphene composite copolymerized white sphere and a condensing agent;(b) cooling to obtain phosphonylated product;(c)subjecting the obtained phosphonylated product to an acidification hydrolysis reaction with an acid at 50-180degrees Celsius, and after the reaction is completed;(d)cooling to room temperature, and performing post-treatment to obtain an exchange resin.
