采用批处理等温吸附解吸试验，研究了初始C u2＋浓度、壳聚糖用量、吸附时间、p H值和温度等单因子对壳聚糖吸附C u2＋的影响，在此基础上采用正交试验获得最优吸附条件为：壳聚糖用量0.025 g/L ，温度35℃，吸附时间60 min ，初始Cu2＋浓度1000 mg/L ，得出最大吸附量为256 mg/g ；因子影响排序由大到小为：壳聚糖用量，温度，初始Cu2＋浓度，吸附时间．吸附铜后的壳聚糖，制作壳聚糖载铜灭藻剂（CCA ），其Cu2＋释放动力学特征可用Elovich方程、Langmuir方程和二级动力学方程加以描述．pH值和CCA的初始用量对Cu2＋释放量有显著影响．

The batch adsorption-desorption experiments have been conducted to determine the effects of single factors involving initial Cu2+ ,chitosan dosage ,adsorption time ,pH and temperature on adsorption capacity of chitosan on Cu2+ ,and optimal adsorption condition has been achieved through orthogonal test as follows :chitosan dosage 0 .025 g/L ,temperature 35℃ ,adsorption time 60min ,initial Cu2+1 000 mg/L .The impact of factors is ranked in order as chitosan dosage> temperature>initial Cu2+ >adsorption time .T he data of release kinetics of Cu2+from CCA is conformed to Elovich equation ,Langmuir equation as well as second dynamic equation while pH and initial dosage of CCA had obvious impact on release quantity of Cu 2+ .
