An Investigation of the Sorption/Desorption of Organics from Natural Waters by Solid Adsorbents and Anion Exchangers

摘要

The results of laboratory and operational tests at thermal and nuclear power stations on anion exchangers and solid adsorbents of makeup water treatment plants with regard to the sorption/desorption of organic substances in natural water and condensate are presented.The resins Amberlite~(TM~1) IRA-67,IRA-900,IRA-958CI,Purolite~R~2 A-500P,Dowex~(TM~3) Marathon,and others were tested.Retention of up to 60-80 % of the "organic" material on the anion exchangers and organic absorbers installed at different places in the technological scheme of the water processing unit was attained.The possibility of a partial "poisoning" of the resins and the degradation of the working characteristics over the first year of operation are discussed.
