Lanlang CH030
Macroporous aminophosphonic chelating resin
Used for brine softening, refining in ion membrane alkaline production.
Lanlang CH030 is a weak acid, macroporous, chelating resin with amino phosphonic acid groups. This structure is good for the chelating with heavy metal ions.
Compared with the chelating resin with amino carboxylic acid groups, resins with amino phosphonic acid groups are much easier to chelate with certain cation ions.
Lanlang CH030 (amino phosphonic acid) is more suitable for purificating the second brine during production of membrane caustic soda.
