中文摘要：

文章讨论了溶液的p H值、吸附时间、吸附温度、羧甲基壳聚糖的用量等因素对羧甲基壳聚糖吸附Ce（Ⅳ）性能的影响.结果表明,在25°C,p H值为6,吸附时间20 min条件下羧甲基壳聚糖对Ce（Ⅳ）的吸附容量、吸附率达到最大值,最大吸附量为96.21 mg/g,最大吸附率为96.22%.羧甲基壳聚糖对Ce（Ⅳ）的吸附行为符合Langmuir吸附等温线.

英文摘要：

In order to explore the Ce （IV）adsorption properties of carboxymethyl chitosan, the effect of pH, adsorption time, adsorption temperature and carboxymethyl chitosan dosage and other factors on Ce （IV） adsorption were studied. The results show that Carboxymethyl Ce （IV） adsorption capacity and adsorption rate reached the maximum under the room temperature of 25 ℃, pH value of 6 and the adsorption time of 20 min. The maximum Ce （IV）adsorption capacity and adsorption rate of carboxymethyl ehitosan were 96.21 mg/g and 96.22 %, respectively. Ce（IV）adsorption on Carboxymethyl chitosan fitted the Langmuir adsorption isotherm.
