以自合成的5.0μm单分散大孔亲水交联聚甲基丙烯酸环氧丙酯（PGMA-EDMA）微球为基质，与亚氨基二乙酸键合，合成了亲水性阳离子色谱固定相。用3.5 mmol/L甲烷磺酸作淋洗液，在流速为1.0 mL/min下，对二乙醇胺、Na+、NH4+、K+混合样及有机胺和铵离子混合样进行分离。将其用于黄纸板中阳离子的分离测定，与原子吸收法（AAS）对照，测定结果基本一致。
以自閤成的5.0μm單分散大孔親水交聯聚甲基丙烯痠環氧丙酯（PGMA-EDMA）微毬為基質，與亞氨基二乙痠鍵閤，閤成瞭親水性暘離子色譜固定相。用3.5 mmol/L甲烷磺痠作淋洗液，在流速為1.0 mL/min下，對二乙醇胺、Na+、NH4+、K+混閤樣及有機胺和銨離子混閤樣進行分離。將其用于黃紙闆中暘離子的分離測定，與原子吸收法（AAS）對照，測定結果基本一緻。

A hydrophilic weak acidic cation stationary phase was synthesized by chemical modification of iminodiacetic ac?id on the base of 5.0μm monodisperse macroporous hydrophilic poly(glycidylmethacrylate-co-ethylenedimethacrylate) (PGMA-EDMA)beads. The mixture of diethanolamine,Na+,K+,ammonium(NH4+)and the mixture of organic amines and ammo?nium can be separated by the elution with 3.5mmol/L methyl vitriol at 1. 0 mL/min. The column was used for the separation of cations from strawboard,The obtained result was consistant with that of AAS method,the effect of resolution is almost same.
