摘要：

A high-performance liquid chromatographic method was developed for the determination of sulphide in water-involves precolumn derivatization of sulphide with 2-iodo-1-methylpyridinium chloride to form 1-methyl-2-thiopyridone, followed by reversed-phase HPLC separation and UV detection. A linear calibration graph was obtained over the range 0.04-50 mug of S2- in 10 ml of final analytical solution and the relative standard deviations were 0.2% at the 1 mug/ml and 3.2% at the 10 mug/l sulphide levels. The proposed method is tolerant towards thiols and many common cations and anions.
