Description

Chemiluminescence (CL) with a flow-injection method is reported for the determination of thiabendazole (TBZ) fungicide based on its enhancement effect on diperiodatocuprate(III) (DPC)–sulfuric acid–CL system. The calibration graph was linear in the concentration range of 1 – 2000 μg L−1 (R2 = 0.9999, n = 8) with a limit of detection (S/N = 3) of 0.3 μg L−1. The injection throughput was 160 h−1 with relative standard deviations (RSD, n = 4) of 1.1 – 2.9% in the concentration range studied. The experimental variables e.g., reagents concentrations, flow rates, sample volume, and PMT voltage were optimized, and the potential interferences were investigated individually. The method was successfully applied to the determination of TBZ in water samples showing good agreement and recovery in the range of 92 ± 2.2 – 108 ± 3% (n = 3) using dispersive liquid–liquid micro-extraction (DLLME). The possible CL reaction mechanism for DPC–sulfuric acid–TBZ is also discussed.
