Chelating resin for precious metals recovery, Gallium recovery

Lanlang ¬ TY CH550 is a sort of chelating resin which has weakly acidic iminodiacetic acid [-CH2N-(CH2OOH)2] in the styrene / DVB copolymer with special macroporous structure.
This product can fix and chelating one or several kinds certain cation in a great range even in the solution with high content. It is used mainly to separate and recover the precious metals ion, especially for the secondary refining of salt brine when the content of Strontium is near or higher than the content of calcium in the process of ion membrane alkaline producing. TY CH550 is also used to remove cooper, nickel, cobalt, zinc from waste water.

TY CH550 is a weakly acidic, macroporous cation exchange resin with chelating iminodiacetate groups for the selective extraction of heavy metal cations from weakly acidic to weakly basic solutions. Divalent cations are removed from neutralized waters in the following order: Copper > Vanadium (VO2+) > Uranium (UO22+) > Lead > Nickel > Zinc > Cadmium > Iron(II) > Beryllium > Manganese > Calcium > Magnesium > Strontium > Barium >>> Sodium.

It is especially suitable for use in the following applications: » selective removal of trace heavy metals from effluents of the metal surface finishing industry, even in the presence of high calcium concentrations » recovery of useful metals from electroplating rinse waters » removal of metal contaminants from processing baths » concentration, extraction and recovery of heavy metals from hydrometallurgical solutions » removal of heavy metals from contaminated ground water for the purpose of potable water production or ground water remediation.
