Remarks: |
Based on the reversed phase ion-pair chromatography, the retention behaviour of thiourea, polysulfide, ammonium sulfide and ammonium thiocyanate were discussed under different conditions such as ion pair reagent and its concentration, ion intensity and organic reagent. It was testified that the concentration of ion pair reagent, pH and the volume ratio of tetramethylene-oxide in mobile phase played important roles in the retention behavior of ammonium sulfide and ammonium thiocyanate. The best analytical results were obtained by using a C18 column with a mobile phase comprising a 20:79:1 (% v/v) mixture of methanol-water-tetramethylene-oxide, pH 6.64, containing 3.0 mmolL-1 ammonium tetrabutyl bromide and 6 mmolL-1 KH2PO4-K2HPO4 buffer. Column temperature and detection wave were controlled at 25ºC and 220nm, respectively. Linearity of the working curve was investigated with correlation coefficients of 0.9989-0.9999, and the relative standard deviation was below 4.9%. The proposed method had been successfully used in the samples determination.
