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．显示利用壳聚糖制作甲醇吸附剂的潜在应用前景
Porous polyethylene glycol was used as additive to prepare a granular chitosan adsorbent with micropore structure and its adsorption and desorption properties to methanol were studied. The results showed that the chitosan particles with micropore structure had strong adsorption capacity to methanol. The adsorption capacity reached 1790 mg / g at room temperature (31 ℃). At the same time, it can remove most of the methanol in a certain period of time. The potential application of chitosan as a methanol adsorbent is shown
