摘要

选取板栗内皮作为吸附剂，在实验室条件下，通过振荡吸附的方法研究了板栗内皮对pH 2.0的酸性废水中，镉、铅、铜、锌4种重金属离子的吸附特性。研究结果表明，当板栗内皮的加入量为30 g/L，反应时间1 h，达到对溶液中4种重金属离子的最大去除率，分别为Cd 98.9%、Pb 99.6%、Zn 98.9%、Cu 98.7%；热力学实验结果表明，板栗内皮对4种重金属离子的吸附容量分别为Cd 3.2、Pb 90.8、Zn 27.3、Cu 52.4 mg/g；动力学实验结果表明，吸附反应在60 min内可以

Abstract

This study reported the feasibility of adsorption of heavy metals from acidic solution using chestnut inner shells (CIS)

an environmentallyfriendly natural adsorbent. The adsorption characteristics of CIS for heavy metals were studied by a series of lab scale experiments. The result of adsorption test shows that CIS gives effective removal of heavy metals from acidic solution (pH 2)

attaining Cd 98.9%

Pb 99.6%

Zn 98.9%

Cu 98.7% with addition of 30 g/L CIS within 1 h. Thermodynamical test shows that the adsorption capacities of CIS for four kinds of heavy metal are Cd 3.2

Pb 90.8

Zn 27.3

Cu 52.4 mg/g. A kinetic test shows that the adsorption equilibrium is attained within 1 h

and the kinetic behavior of adsorption could be described by Elovich Model. The relationship between the adsorption rate and reaction time is in adverse proportion. At the same time

the adsorption of CIS on Cd

Zn is followed by specific order

Pb2+>Cd2+>Cu2+>Zn2+. 
