D403

Product D403 is a chelating ion exchange resin with imino diacetic acid groups [-N-(CH2COOH)2] attached to the benzene rings of a copolymer bead of styrene and divinylbenzene with a macroporous structure. Its selectivity for metal ions is similar to that of EDTA and superior to strong acid or weak acid cation exchange resins. When monovalent and divalent metal ions coexist in solution, it selectively adsorbs only divalent ions. This product is suitable for removing Ca2+ and Mg2+ from brine in electrodialysis salt water purification and is also used for wastewater treatment and recovery of precious metals.
