摘　　要：直接进水样气相色谱法快速测定水中的硝基苯，分别采用2％QF－1＋1．5OV－1ChromosorbWAW－DMCS（80-100目）（Ⅰ）和5％聚乙醇-6000101白色担体（40－60目）（Ⅱ）为固定相的两种不锈钢柱，FID检测器，对硝基苯完成分离，本法进样4μl的检测限为0．25mg／L，能满足应急污染监测的需要。对柱Ⅰ，提出了一种改善分离的方法．A Rapid GC method for determination of the nitrobezene in water is studied. The water sample is injected directly into the 1102 GC equipped with FID. Two column,packed with 2%QF-1+1. 50V-1 ad-sorbed on chromosorb W AW-DMCS (80～100 mesh) or 5% polyethylene glycol 6000 on 101 white carrier (40～60 mesh) are compared. on the base of exper iments,this method is found to be accurate,rapid and sen-sitive enough for determining nitrobezene in water at ppm levels,and can be applied in emergency monitoring.A modified technique is proposed to improve the seperation of nitrobezene from water.
