| This thesis includes two parts. Part one(Chapter one) is review. Part two(Chapter two to Chapter five) is research reports.In the first part, the present state of organophosphorous pesticides residues research and basic Knowledge of chemiluminescence (CL) were introduced. And the present applications of the CL method in organophosphorous pesticide residues and other fields were also reviewed in this part.In part two, the flow injection CL assay of some organophosphorous pesticides (methamidophos,trichlorphon,dimethoate,triazophos) were investigated.Methods for the determination of these organophosphorous pesticides were proposed,and were applied to the vvegetable samples determination.The CL reaction mechanisms were also discussed.In chapter two,a method for the determination of methamidophos based on the enhancement of chemiluminescence(CL) of luminol-potassium ferricyanide in basic medium by flow injection CL analysis has been established. The calibration graph is linear for1.0×10-8-1.0×10-5g/mL with a detection limit (S/N=3) of 5.3×10-9g/mL,the relative standard RSD is 2.0%for 1.0×10-6g/mLmethamidophos(n=11).The method was simple, fast,sensitive and cheap,and was applied successfully to the determination of methamidophos in vegetables,recovery is between 93.0%-94.4%. The system's reaction mechanism was also discussed.In chapter three, based on the chemiluminescence(CL) enhancement of luminol-H2O2 in basic medium,a flow-injection CL method for the determination of trichlorphon has been proposed. The calibration graph is linear for 1.0×10-8-1.0×10-5g/mL,the detection limit (S/N=3) is 3.2×10-9g/mL, the relative standard RSD is 1.10% for 1.0×10-7g/mL trichlorphon(n=11). The method was applied to the determination of trichlorphon in vegetable ,recovery is between 88.5%-92.6%. The system's reaction mechanism was also discussed.In chapter four,based on the chemiluminescence(CL) can be greatly enhanced by adding dimethoate in the basic medium,a a flow-injection CL method for the analysis...
