摘　　要：利用高效液相色谱法测定了３,３’－二氯联苯胺盐酸盐合成工业酸性废水中的污染物,色谱柱为Ｚｏｒｂａｘ－ＯＤＳ,流动相为乙腈－水(７０/３０,Ｖ/Ｖ),流速为０．５ｍｌ·ｍｉｎ－１,柱温４２℃,检测波长２８０ｎｍ．建立了废水水样预处理方法,主要污染物回收率在９０%以上．酸性废水中污染物包括３,３'－二氯联苯胺盐酸盐、邻氯苯胺等．A reversed-phase high performance liquid chromatography method was diescribed for the deter-mination of pollutants in wastewater from synthesis of 3,3'-dichlorobenzidine hydrochloride.Station-ary phases of Zorbax-ODS and mobile phase of acetonitrile-water (70: 30, V/V) were applied forthis purpose.The analysis revealed that the wastewater contained several pollutants, including3,3'-dichlorobenzidine hydrochloride,o-chloroaniline and other two unknown ones.
