摘要
指出了气相色谱法测定水质苯系物存在的不足。提出用 3%有机皂土 - 34+2 .5 %邻苯二甲酸二壬酯混合涂渍的 10 1担体 (6 0目~ 80目 )不锈钢色谱柱分离苯系物 ,可在 19min内分离水样中 7种苯系物 ,对二甲苯与间二甲苯等难分离物质对可完全分离。改进后的样品前处理顶空装置操作简单、安全 ,可连续自动振荡 。
The disadvantage to determine benzene using gas chromatography was illustrated. Using the 101 supporter (60 mesh~80 mesh) which was coated by 3% bentone -34 and 2.5% DNP and stainless steel chromatographic column to separate benzene. Within 19 min, 7 kinds of benzene were separated. The improved pre-treatment procedure was operation- easy and safe, and can treat many samples in the same time
