摘要：A sensitive, simple and rapid flow-injection chemiluminescence (FI-CL) method is described to determine tsumacide pesticide residue based on the CL reaction of the alkaline degradation product of tsumacide with acidic KMnO4 when rhodamine 6G was present. Under the optimum conditions, the relative CL intensity is linear with the concentration of tsumacide in the range of 2.0 x 10(-3)-0.20 mg/L. The detection limit is 6.6 x 10(-4) mg/L (3 sigma) and the relative standard deviation for 2.0 x 10(-2) mg/L tsumacide solution was 2.28% (intra-day) and 4.85% (inter-day). The proposed method has been applied to determine the residue of tsumacide in vegetable samples and the recovery test is very satisfactory. Copyright (C) 2007 John Wiley & Sons, Ltd.
