Abstract

The treatment of leachables of cation exchange resin using advanced oxidation process was studied. By using this method

the organic leachables was degraded and the sulfonic acid group was converted into SO_4~(2-). The degradation of resin leachables in UV

Fenton

UV/H_2O_2 and UV/Fenton systems was studied experimentally. The results show that

the UV/Fenton system has remarkable effect on treating the resin leachables. In addition

the effects of UV lamp power

H_2O_2 concentration

FeCl_2 concentration

pH value and reaction time on the degradation process were investigated. It shows that

under certain conditions

the sulfonic acid group could be completely degraded

the removal rate of the total organic carbon was as high as 97%. This UV/Fenton method provides an important reference for determination and evaluation of the leaching property of cation exchange resins.
