羧甲基壳聚糖对Mg^(2+)的吸附性能研究

Study on Carboxymethyl Chitosan for Adsorption of Mg^(2+)

研究羧甲基壳聚糖对Mg2+的吸附作用,探讨了溶液的pH、吸附时间、温度等因素对吸附率的影响。实验表明,在pH值为4~5时,羧甲基壳聚糖对Mg2+的吸附性能很好,其饱和吸附容量为106mg/g,方法的相对标准偏差为9.6%。

Adsorption of Mg2＋ on carboxymethyl chitosan was studied. The effects of variousfactors, such as pH value, reaction time and temperature on the adsorption efficiency were discussed. The experimental results showed that the adsorption efficiency of carboxymethyl chitosanwasfine when pH was 4 - 5. The saturated adsorption capacity of carboxymethyl chitosan is 106 mg/g and the relative standard deviation of this method is 9.6%.
