1. Brief Introduction:
The product is a type of cation exchange resin with the carboxylic acid radical(-COOH) on macroporous crylic acid copolymet which is used for industrial wastewater disposal ,especially for removing bicarbonate, carbonate and other basic salt .It can also be used for recovery processing of zinc and nickel waste solution and purification of biochemical drug.
LH-113 resin series are made up of three types, LH-113 is a kind of commonly used products, LH-113 FC is widely used in front room bed and fluidized bed system and LH-113 SC is applied to bunk bed system.
