The rates of adsorption of hydrochloric acid by 16 weakly basic ion-exchange resins have been measured, together with the rates of adsorption of sodium hydroxide by 16 weakly acidic ion-exchange resins. The results obtained for the weakly basic resin "Amberlite IRA-93" confirm that the adsorption ra

โฆ Synopsis
Weakly basic amine resins are an essential component of thermally regenerable systems, but they have the inherent disadvantage of oxidation under the hot . regeneration conditions unless oxygen is removed from the feed water. Removal of oxygen from the hot (SO-90ยฐC) regeneration water poses few problems. but the reduction of oxygen (0 the level of 0.05-0.1 mg/l required in the ambient temperature feed water is n relatively costly operation. This is now considered essential
