摘　　要：通过实验探讨了离子交换树脂对乙醇溶液中甘油的吸附作用。实验结果表明，凝胶型树脂对甘油的静态吸附容量大于大孔型树脂，且一般随温度降低而增大；在所试验的几种树脂中，２０１×４（ＯＨ型）具有较大的动态吸附容量（３３．７ｍｇ甘油／ｍｌ湿树脂）。The adsorption of glycerol in ethanol solution by ion exchange resin has been studied experimentally.It was found that the static adsorption capacities of glycerol by resins of gel type were better than those of big aperture type and the capacities increased with the decrease of temperature;among the tested resins,201×4(Na type) had a relatively larger dynamic adsorption capacity(33.7 mg glycerol/ml resin).
