【摘要】 在ODS键合相柱上,以含0.2mol/L十二烷基硫酸钠（SDS）的甲醇/水（40/60）溶液为流动相,NienAA₂,CuenAA₂和NiDDTC,CuDDTC二类中性金属螯合物分别获得良好分离。论证了在高浓度甲醇溶液中,SDS能形成胶束。由于胶束增溶作用,SDS在分离中性金属螯合物的反相色谱体系中起着有机改性剂的作用。更多还原

【Abstract】 Excellent separations for two types of neutral chelates NienAA₂, CuenAA₂ and NiDDTC, CuDDTC, can be acquired respectively on ODS-column with a mobile phase of 40%（V/V） methanol aqueous solution containing 0. 2 mol/L sodium dodecyl sulfate （SDS）. The article proves that the surfactant SDS can form micelle in methanol aqueous solution of high concentration, and that SDS acts as an organic modifier due to micellar solubilization in separating neutral chelates by reversed-phase chromatography.更多还原
