Chelating amino phosphonic resins for second brine purification of producing membrane caustic soda

Product Overview

Description

SEPLITE^® LSC 750 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.

SEPLITE^® LSC 750(amino phosphonic acid) is more suitable for purification the second brine during production of membrane caustic soda.

SEPLITE^® LSC 710(amino carboxylic acid) is more suitable for removing heavy metal ions, like copper recovery etc.

 

For SEPLITE^® LSC 750(amino phosphonic acid), it enjoys the advantage of below:

l Superior mechanical and excellent resistance to osmotic shock

Good mechanical strength, low loss, less topping annually, stable Kinetics performance

l High chelating capacity

High chelating capacity leads to bigger amount of brine treated per cycle

l More uniform for particle size

Excellent running kinetics during regeneration
