Abstract:

A new flow-injection chemiluminescence (CL) method is described for the determination of carbendazim. The method is based on the CL reaction of luminol and hydrogen peroxide (H2O2). Carbendazim can greatly enhance the chemiluminescence intensity in sodium hydroxide-sodium dihydrogen phosphate (NaOH-NaH2PO4) medium (pH = 12.6). Under the optimum conditions, the linear range for the determination of carbendazim is 2.00 x 10(-8) to 2.00 x 10(-6) g mL(-1) with a detection limit (S/N = 3) of 7.24 x 10(-9) g mL(-1). The relative standard deviation is 1.8% for 1.0 x 10(-7) g mL(-1) carbendazim (n = 8). The proposed method has been applied to the determination of carbendazim in tap-water samples. Furthermore, the possible enhanced CL mechanism is discussed by examining the CL spectra and fluorescence spectra.
