摘　　要：本文研究了高级氧化法处理阳离子交换树脂溶出液,降解有机溶出物,将其中的磺酸基团转化为SO_(4)^(2-),测定树脂溶出特性的方法;实验研究了树脂溶出液在UV、Fenton、UV/H_(2)O_(2)、UV/Fenton等体系中的降解作用,并探究了紫外灯功率、H_(2)O_(2)浓度、FeCl_(2)浓度、pH值和反应时间等因素对降解过程的影响。结果表明:UV/Fenton体系处理树脂溶出液时效果显著;在一定条件下,磺酸基团可完全降解,总有机碳降解率高达97%。该树脂溶出液UV/Fenton氧化处理法为测定和评价树脂溶出特性提供了参考。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_(2)O_(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_(2)O_(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.
