摘　　要：[目的]建立高效液相色谱法测定百菌清中六氯苯、十氯联苯的方法。[方法]采用Waters2998高效液相色谱仪（配备WatersSymmetryC18不锈钢色谱柱），以甲醇一四氢呋喃一水为流动相，在217nm波长下对百菌清中六氯苯、十氯联苯含量进行测定。[结果]在0．05～2．0mg／L范围内，六氯苯、十氯联苯线性关系良好，平均回收率为98．5％和97．9％，六氯苯的相对标准偏差为3．4％。[结论]该方法能快速、准确测定百菌清中六氯苯和十氯联苯的含量。[Aims] The HPLC （high performance liquid chromatography） method for the determination of hexachlorobenzene and decachlorobiphenyl in chlorothaloni was established. [Methods] The contents of hexachlorobenzene and decachlorobiphenyl in chlorothaloni were analyzed by using Waters 2998 HPLC （with Waters Symmetry C18 stainless steel column）, with methanol-tetrahydrofuran-water as mobile phase at 217 nm. [Results] The linear correlation coefficients were good for hexachlorobenzene and decachlorobiphenyl at 0.05-2.0 mg/L, the average recovery rates of hexachlorobenzene and decachlorobiphenyl were 98.5 and 97.9%, respectively. In addition, the relative standard deviation ofhexachlorobenzene was 3.4%. [Conclusions] This method can be used to determine the contents of hexachlorobenzene and decachlorobiphenyl in chlorothaloni, which has the advantages of fast speed and high accuracy.
