摘　　要：以致孔剂聚乙二醇为添加剂，制备出一种具有微孔结构的颗粒状壳聚糖吸附剂，并研究了其对甲醇的吸附及脱附性能．结果表明，这种具有微孔结构的壳聚糖颗粒对甲醇具有很强的吸附能力，在室温（３１ ℃） 下，其饱和吸附量达１ ７９０ ｍｇ／ｇ ．同时，它在一定时间内能将甲醇大部分脱附．The microvoid adsorbent was made from chitosan by using polyethylene glycol as the additive. Its adsorption desorption properties for methylic alcohol were studied. The results showed that the chitosan adsorbent has a good adsorption property for methylic alcohol and the saturation capacity of adsorption is 1 790 mg/g at room temperature. Meanwhile, it mostly desorbed methylic alcohol within a given time. Chitosan’s prospective uses as the adsorbent for methylic alcohol were showed.
