【摘要】 研究了高脱乙酰度壳聚糖 (CTS)对镧 (Ⅲ )离子的吸附性能。探讨了溶液的初始浓度、pH值、时间对吸附性能的影响。结果表明 ,壳聚糖对镧 (Ⅲ )离子有较高吸附性 ,最高吸附率达 80 %以上 ;其吸附行为满足Langmuir等温式。更多还原

【Abstract】 The adsorption capacity of La 3+ ions on chitodan was studied .The effects of the centration, pH, time ,temperature on adsorption capacity were investigated .Chitodsan has a good adsorption capacity to La(Ⅲ) ion. The highest rate of adsorption reached about 80 % on CTS . Its behavior was coincided with the equation of Langmuir.更多还原
