ZGD851 macroporous imine diacetoxyl chelating resin
1. Description
The “Hydorlite” ZGD851 resin is a sort of chelating resin which has weakly acidic imine diacetoxyl [-CH2N-(CH2OOH)2] in the cinnamene styrene and diethenoid benzene 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.
