| Abstract: | A rapid GC method for determination of the nitrobenzene in water is studied.The water sample is injected directly into the 1102 GC equipped with FID.Two columns,packed with 2%QF|1+1.50V|1 adsorbed 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 experiments,this method is found to be accurate,rapid and sensitive enough for determining nitrobenzene in water at ppm levels,and can be applied in emergency monitoring.A modified technique is proposed to improve the seperation of nitrobenzene from water. |
