Regeneration of strongly basic anion exchangers is influenced by the quality of caustic
available. Chloride, chlorate and ferrate ions are potential contaminants in caustic that may
affect resin regeneration efficiency and stability. Sodium chlorate itself has very little
oxidative properties in neutral or alkaline solutions, but in acid conditions (i.e. during resin
exhaustion), chloric acid is generated which is a powerful oxidizing agent.
