Lanlang ® CH020
Macroporous iminodiacetic acid chelating resin
Used for cooper, nickel, cobalt, zinc removal
Lanlang ® CH020 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. CH020 is also used to remove cooper, nickel, cobalt, zinc from waste water.
