The ion-exchange membrane method is the most advanced method of caustic soda production at present, but the ion-exchange membrane method has high requirements on the quality of the brine of the electrolyzed raw material, and the iodide in the brine can cause the current efficiency to decrease and shorten the service life of the ion membrane. The ion exchange method has the characteristics of regeneration and recycling, and has low energy consumption, which is an ideal method for iodine removal in chlor-alkali industry.
The special ion exchange resin for iodine removal provided by Kingshan resin has the advantages of high selectivity, large exchange capacity, high mechanical strength and convenient regeneration treatment, and is widely used in the chlor-alkali industry.
