D418
D418 macroporous styrene chelating resin is a cation exchange tree with a phosphoramidite functional group. This resin is basically chelating to all divalent metal ions, especially for alkaline earth metals with special selectivity. D418 is an ideal resin suitable for salt water softening. It can be used to remove divalent metal cations from industrial wastewater and other industrial water. D418 is mainly used for refining secondary brine in the process of making caustic soda by ion membrane method. It can reduce calcium and magnesium ions in secondary brine to 20 ppb, and resin exchange Both capacity and mechanical strength are better than similar aminolin acid resins abroad. In addition, D418 can also be used for the recovery of heavy metals in electroplating wastewater.

1. The resin contains water and should be kept at a temperature of 5-40ºC during storage and transportation to prevent freezing at low temperatures and mildew at high temperatures, which affects its use.
2. Because the resin is exposed to the air or loses water for any reason, do not directly inject water to prevent the resin from floating. It can be impregnated with ethanol to restore it to a wet state and then cleaned with water.
3. The adsorbed substance (solution) should be subjected to impurity removal, filtration, and clarification before being put on the column, so as to avoid impurities entering the resin column as far as possible, so as not to cause acute resin poisoning and affect the use.
4. Resin is interrupted. After washing with water, it should be stored in soaked clean water and changed regularly to prevent contamination. It can also be immersed in saturated saline or ethanol for long-term storage.
