✦ Synopsis

The chemihuninescence (CL) reaction of bisf2,4,6-trichlorophenyl) oxalate with hydrogen peroxide was applied to the detection of fluorescent organotin-quinoline complexes using a flow-injection system. Four organotin compounds, i.e., di-n-butyltin dichloride (DBTC), diphenyltin dichloride (DPTC), tri-n-butyltin chloride (TBTC) and triphenyltin chloride (TPTC), were examined in conjunction with 2-methyl-Shydroxyquinoline. Factors affecting the CL intensity such as solvents, reagent concentrations, pH and flow-rate were studied. The detection limits for DBTC, DPTC, TBTC and TPTC were 0.5 PM (3 ng), 1.25 PM (8.6 ng), 25 PM (162.7 ng) and 100 PM (770.9 ngJ, respectively, with a signal-to-noise ratio of 3.
