摘　　要：用质谱法鉴定出间苯二甲酸二甲酯 5 磺酸钠生产废水中的几种主要有机物 ,并利用液 -质联用进行定量分析。对比了几种吸附树脂对它们的静态吸附和脱附效果 ,结果表明 ,生产废水中主要含有 3,5 -二羧基苯磺酸 (SIPA)钠和间苯二甲酸二甲酯 5 磺酸 (SIPM)钠 ,用NDa15 0树脂吸附和用甲醇脱附对废水中有机物的资源化具有较好的效果。In this paper several organic compounds in the wastewater of producing dimethyl 5-sulfoisophthalate sodium salt were identified and analyzed quantificationally by combined HPLC with MS,and the comparisons of static adsorptions and desorbing efficiencies of some adsorption resins were made.The results show that 3,5-dicarboxylsulfoisophthalate sodium and dimethyl 5-sulfoisopthtalate sodium salts exist mainly in the process of producing wastewate,and the NDa150 resin and methanol will be effective for treatment of wastewater and reuse of organic compounds.
