经修饰的桔子皮对重金属Zn~(2+)的吸附研究

传统去除重金属离子的方法很多,但都存在某些不足之处,而生物吸附法因其材料易得,价格低廉,去除效果好而受到人们的青睐。本文通过桔子皮生物吸附剂对锌离子吸附动力学、最大吸附量的研究可以得到以下结论:桔子皮生物吸附剂对锌金属离子的吸附可以分成三个阶段。桔子皮生物吸附剂吸附重金属锌离子的最大吸附量的吸附等温线都非常符合Langmuir方程(R2=0.92-0.98)。

Study on the Preparation of Biosorbents Orange Peels and Biosorption of Heavy Metal Zn2+ Ions

Some more tradition methods to treat Zn are introduced for heavy metal removal.But such methods as physical and chemical ones have different shortcomings.A new kind of method is developed.In this paper,preparation of orange peel cellulose biosorbents and its biosorption behaviors of copper and lead ions are studied.It can come to the conclution that there periods in the process of biosorbents.And it accords Langmuir(R2=0.92-0.98).
