Chlor-Alkali Electrolysis

概要

Electrolysis of concentrated brine (NaCl solution) produces three essential industrial chemicals simultaneously: chlorine gas at the anode, sodium hydroxide solution at the cathode, and hydrogen gas as a byproduct. Modern membrane cells use ion-exchange membranes to separate products and achieve 95%+ current efficiency.
