A novel flow injection chemiluminescence(FI-CL) system for the determination of isoprocarb is presented.It was based on the chemiluminescence reaction of sodium hydrosulfite with Ce(Ⅳ) in a vitriol acid solution.The emission intensity can be obviously enhanced by isoprocarb.The proposed method is very sensitive,simple and quick.The enhanced value of chemiluminescence intensity was proportional to isoprocarb concentration in the range of 0.1~10 mg/L(r=0.999 7).The detection limit was 80 μg/L and the relative standard deviation was 3.3% for 1.0 mg/L isoprocarb(n=11).This method was successfully applied to the determination of isoprocarb in rice and water.The recovery was 96.1%~99.4%.
