英文摘要

A novel, sensitive and accurate method has been successfully developed to the simultaneous determination of 3 monochlorophenols (MCP) in drinking water samples by ion chromatography (IC) coupled with an atmospheric pressure chemical ionization mass spectrometry in the negative mode. Drinking water was preconcentrated by solid-phase extraction (SPE). The IC separation was carried out with an, IonPac(R) AS18 analytical column (250 mm x 4.0 mm) and an IonPac(R) AG18 guard column (250 mm x,4.0 mm) using 15 mmol/L KOH containing 10% acetonitrile as mobile phase in isocratic mode at a constant flow rate of 1.0 mL/min. The molecular Ion m/z 1.27 [M - H](-) was selected for the quantification in selected ion monitoring (SIM) mode. The relative standard deviations of intra-day and inter-day were less than 8.6% and 10.5% respectively. The limits of quantification (LOQ) in water samples were 0.02, 0.01 and 0.01 mu g/L for 2-MCP, 3-MCP and 4-MCP, respectively. The method allows the 3 target compounds in water samples to be determined at mu g/L levels, and it has been, successfully applied to the routine analysis.
