工业废水中苯的高效液相色谱分析

HPLC analysis of benzene in industrial waste water

采用高效液相色谱法对橡胶厂排放废液中微量苯进行了测定 ,分离柱为ZorbarEclipsXDBC8,淋洗液为甲醇———水 (70 :3 0 ) ,该方法操作简便 ,分离条件好 ,回收率为 99%～ 10 1% ,变异系数为 0 .3 3 %。

Rapid determination method of benzene with high performance liquid chromatography was introduced with Zarbax Eclips XDBC 8 as separator column and methanol-water(70∶30)as washing liquid.The method is easy to operate and has good separation condition.Its percent recovery is between 99.01%～101.67% and coefficient of variation 0.33%.
