Abstract
The production of commercial quantities of chlorine gas and alkali-metal-hydroxides is performed by electrolysis of brine solutions in a chloralkali cell.
The most advanced technology for this process requires membrane electrolysis cells. For good performance of these cells there is a demand for high purity brines with extremely low levels of divalent cations ( magnesium, calcium, strontium ) and low levels of sulphate anions.
The following discussion describes how ion exchangers with chelating functional groups meet the required specifications.
