Simultaneous separation and determination of Cu(II), Fe(III), and Pb(II) by reversed-phase ion-pair chromatography withN,N,N′, N′-ethylene-diaminetetrakis(methylenephosphonic Acid)

KeyWordsColumn liquid chromatography Ion-paTr chromatography Sulfides Tetramethylene oxide Synthesis and isomerization system Summary A reversed-phase ionpair chromatographic method with tetramethylene oxide as organTc modifier has been developed for the simultaneous separation and detection of the sulfides NH2CSNH2, (NH4)2CS3, (NH4)2S, and NH4SCN. The optimized separation conditions were determined by means of a U7 (76) uniform design experiment, and teiramethylene oxide played an important role in adjusting the retention behavior of(NH4)2S and NHsSCN. The lin earity of the calibration plots far the four components was investigated; correlation coefficients were from 0.9989 -0.9999. The proposed method was successfully applied to the determinatTon of NH2CSNH2, (NH4)2CS3, (NH4)2S, and NH4SCN in synthesis and isomerizatTon sam pies.
