摘　　要：研究了几种树脂对五氯酚钠的吸附能力,其中戊二醛交联的壳聚糖树脂不仅有较好的吸附效果,动态吸附容量为187.5mg/g干树脂,而且易洗脱,洗脱率高达90%以上。Adsorption effects of several adsorption resins for Sodium pentachlorophenate were evaluated .Chitosan resins crosslinked by glutaraldehyde(CS-G)not only had better adsorption capacity ,its dynamic adsorption capacity was 187.5mg/g (dry resin) ,but also had the bestdesorption property ,its desorption rate was above 90% .When 0.01M NaOH and Methanol (50/50 by volume) were used as desorbtion agents.
