The removal of dissolved oxygen (DO) from water was studied using anion exchange resin AV-17-8 in a sulphite form. The effects of various operating conditions, such as water flow rates, height of the resin bed and mineralization of water on the removal of DO have been studied extensively. It was shown that its reducing ability depends on the water ionic composition that affects the desorption rate of the sulphite anions. The possibility of efficient water deoxygenation at ambient temperature was demonstrated. The mechanism of chlorate anions reduction on the anion exchanger was determined.
