摘要： 制备了羧甲基纤维素-单宁基吸附树脂，并研究了吸附树脂对亚甲基蓝的吸附性能。羧甲基纤维素与单宁结合，通过羧甲基纤维素羧基与单宁酚羟基的协同作用，能有效提高吸附树脂对亚甲基蓝的吸附性能，最大吸附容量可达1 300 mg/g。在亚甲基蓝溶液初始质量浓度为1 000 mg/L，吸附剂投加质量浓度为1.5 g/L时，吸附树脂对亚甲基蓝的吸附率可达98%以上，且羧甲基纤维素-单宁基吸附树脂具有较好的重复使用性能。

Abstract: Carboxymethyl cellulose-tannin-based adsorbing resin has been prepared,and the adsorption performances of the adsorbing resin for methylene blue have been investigated. Combining carboxymethyl cellulose with tannin, through the synergistic effect of carboxymethyl cellulose and tannin,can effectively improve the adsorption capability of adsorbing resin for methylene blue. Its maximum adsorption capacity for methylene blue can reach 1 300 mg/g. When the initial mass concentration of methylene blue is 1 000 mg/L,and the mass concentration of the adsorbent added 1.5 g/L,the adsorption rate of the adsorbing resin for methylene blue reaches above 98%. In addition,carboxymethyl cellulose-tannin-based adsorbing resin possesses relatively good performance for repeated use.
