Title:
METHOD FOR RECOVERING PRECIOUS METAL FROM POLYKETONE POLYMERIZATION REACTION WASTE LIQUID
Document Type and Number:
WIPO Patent Application WO/2012/121495
Kind Code:
A2
Abstract:
The present invention relates to a method for recovering a precious metal (palladium) after a polyketone polymerization reaction, and comprises the steps of: (a) generating a first reaction waste liquid by filtering the polyketone produced by the polyketone polymerization reaction with a reaction medium; (b) generating a second reaction waste liquid by drying a slurry of the produced polyketone; (c) recovering the reaction medium and generating distilled waste liquid through distillation of the first reaction waste liquid and the second reaction waste liquid; (d) adsorbing and isolating the palladium using an ion exchange resin from the distilled waste liquid; and (e) recovering the enriched palladium by desorbing the adsorbed palladium on the ion exchange resin.
