【摘要】 以10μm锆胶微球包覆聚苯乙烯制成强酸、弱酸型的阳离子色谱柱填料,具有良好的色谱性能。使用D ionex-120型双柱离子色谱仪,较好地分离碱金属、碱土金属离子及铵离子,比较了不同交换基团对溶质保留的影响。由于锆胶基质具有高的化学稳定性和机械强度,用作离子色谱柱填料有良好的应用前景。更多还原

【Abstract】 A new type of zirconia-based cation exchange stationary phases for ion chromatography(IC) was prepared and evaluated.Three zirconia-based strong and weak acid cation-exchange columns were(eveloped)through cross-linked polymer-encapsulated method.The separation characteristics of the column are presented and applications are discussed.The results show that the maleic-acid-styrene encapsulated zirconia-based(column) has satisfying separation ability for the alkaline metal,alkaline earth metal and amine cations.更多还原
