中文摘要：
采用负载金属离子的配位吸附树脂在不同介质中对羟基羧酸的吸附规律进行研究。考察了吸附介质、树脂基质及所负载的金属离子不同对配位吸附的影响。结果表明，负载Fe^3＋的大孔磺酸型树脂在正己烷体系中对羟基羧酸类成分的吸附效果最佳，且随着羟基取代数目和位置的不同表现出一定的吸附选择性。
英文摘要：
Adsorption of hydroxyl carboxylic acids from none-aqueous system on the ligand exchange adsorbent was investigated in this paper. The effect of the different medium, metal-ion and so on has been researched. The result shows that the hydroxyl carboxylic acids was better adsorbed from n-hexane than other mediums on the ligand exchange adsorbent, D72 in Fe63＋ and has different adsorption selectivity depending on the number and the location of hydroxide.
