摘　　要：采用高效液相色谱法(HPLC)测定城市污水中邻苯二甲酸二丁酯(DBP)和邻苯二甲酸二辛酯(DOP),以十八烷基键合相为固定相,样品前处理使用环己烷液-液萃取的方法。优化了流动相(甲醇和水)流速、比例、进样体积和色谱柱温度,确定了最佳色谱条件。该方法DBP和DOP的线性相关系数均为0.998,检测精密度分别为0.70%和4.47%,三水平加标回收率在82.5%~120.0%之间,最低检出限为0.1μg/L(信噪比S/N分别为4.68和2.17)。城市污水样品中检出了DBP和DOP,均未超过国家标准。开发的高效液相色谱法适用于城市污水中DBP和DOP的检测,具有快速、高效、检出限低等优点。It reported the detection of dibutyl phthalate(DBP)and di-n-octyl phthalate(DOP)in sewage water with high performance liquid chromatography(HPLC)via octadecyl bonded phase as mobile phase.The chromatographic condition was determined and optimized in mobile phase(methyl alcohol and water)flow velocity,proportion,sample injection volume and chromatographic column temperature.With this method the linearly dependent coefficient of DBP and DOP was 0.998,the detection accuracy was 0.70%and 4.47%separately,three-level standard recovery rate was 82.5%~120.0%,and the lowest detection limit was 0.1μg/L(signal to noise S/N was 4.68 and 2.17 separately).DBP and DOP were detected in urban sewage samples,and neither of them exceeded the national standard.The established HPLC method is applicable to detection of DBP and DOP in sewage water,which is rapid,efficient and has a low detection limit.
