%X Mixed solutions of sodium sulphite and sodium carbonate arc used in the absorption of iodine from the waste-gas. Sodium sulphite solutions are ready to be oxidizid by air. Experimental results show that the oxidation rate is remarkable but not very high and greatly influenced by pH values. When Na2SO3 is oxidized by dissolved oxygen. However, when sufficient oxygen is supplied through bubbling air into the solution the concentration of sulphite in the solution decreases rapidly with a character of linear concentration-time relation. The actual process of iodine recovery is described in this paper. It is suggested that fresh solution of sodium su'phite be used for the purpose of decreasing the oxidation.
