摘要
把四(甲醚撑)多产β-二酮型开链冠醚接技到用氨丙基三乙氧基硅烷改性的硅胶小球上,制备出一种新型的开链冠醚键合离子色谱固定相.对其色谱特性进行了考察.用不同比例的甲醇/水作流动相,可对碱金属、碱土金属、过渡金属得到较好的分离.
Tetra (oxydimethyl) poly-β-diketone type non-cyclic crown ether ion chro-matographic stationary phase was prepared by grafting non-cyclic crown ether on modified silica gel. The chromatographic behavior of the stationary phase was studied. Very good separation was obtained for alkali, alkaline earth and transition metals on this stationary phase using various ratio of methanol and water as mobile phase.
