摘　　要：研究了负载金属离子的磺酸型树脂在水、乙醇、乙酸乙酯、正己烷等不同介质中对苯酚、o-苯二酚、m-苯二酚、p-苯二酚、联苯三酚、间苯三酚等酚类成分的吸附性能。结果表明:负载了铜离子的树脂 (D72-Cu^(2+)) 在正己烷中对苯酚的吸附能力较弱,而对 o-苯二酚、m-苯二酚、p-苯二酚、联苯三酚、间苯三酚等具有一定的吸附作用,且随着羟基的数目和空间位置的不同,对上述酚类成分表现出明显的吸附选择性。因此,应用这种具有配位吸附作用的树脂对非水体系中的酚类成分进行吸附分离是可行的,且有望进一步研究将其用于对某些天然活性成分的提取分离。Adsorption of phenol, catechol, resorcin, hydroquinone, pyrogallic and phloroglucinol from water, ethanol and n-hexane on the ligand exchange adsorbent, D72 in Cu2+ form has been investigated. In this paper the result shows that the resin adsorbs these components except phenol effectively from n-hexane and has different adsorption selectivity, depending on the number and the location of hydroxide. Therefore the separation of these components of phenols by the ligand adsorption resin can be achieved from nonaqueous media and will apply in the adsorptive separation or removal of some water insoluble nature products as potential ligand.
