Specialty Ion Exchange Resin for Precious Metallic Gold(Au) Complexes Extraction/Recovery through Electroplating Wastewater Treatment

PRODUCT DATA SHEET:

KP-2012G is an ion exchange resin synthesized with special technology, specializing in adsorbing and extracting metallic gold complexes. This resin has highly complete particles and performs with its excellent regeneration efficiency and rinse effect. It is mainly applied to extracting and recovering strong acid root anions of gold complexes through wastewater treatment after the process of pure-water treatment within electroplating plants.
