| Abstract: | 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. |
