摘　　要：凝结水精处理系统投入运行后,部分核电站蒸汽发生器水及大型火力发电厂炉水中的SO_4^(2-)含量显著上升。为找出其中的原因,利用离子色谱对某001×7型阳树脂溶(浸)出物中有机磺化物的氧化分解行为进行了研究。结果表明,该类型树脂溶(浸)出物中有机磺化物会被氧化剂氧化分解出SO_4^(2-),随温度和时间的增加,氧化分解作用呈上升趋势。水中Fe^(3+)是这种氧化分解作用的催化剂。同时,给出了阳树脂溶(浸)出溶液中有机磺化物可转换成SO_4^(2-)最大值的估算方法,用以判断阳树脂溶(浸)出有机磺化物的稳定性。The contents of SO4^2- increase significantly in the steam generator water of some nuclear power plants and the boiler water of large thermal power plants due to the applications of the condensate polishing treatment system. To find the root cause behind this, the oxidation and decomposition characteristics of organic sulfonate in the leachables （extracts） from 001×7 cation resin is studied by using ion chromatography. The results illustrate that the organic sulfonate in the leachables（extracts） from this type of cation resin will be oxidized and decomposed to SO4^2- by oxidant; with the temperature and time increasing, the oxidation and decomposition show an upward trend. Fe^3＋ in the water is the catalyst for this oxidation and decomposition. In addition, the estimation method is also put forward for calculating the maximum organic sulfonate convertible to SO4^2- in the leachables（extracts） to determine the stability of the organic sulfonate in the leachables （extracts）.
