摘　　要：以活性炭纤维作为去除水中镉、镍、铜三种重金属离子的吸附剂,考察了震荡时间、水样pH对吸附效果的影响。测定了三种离子的吸附等温线,采用Langmuir和Freundich模式对吸附平衡实验数据作了线性模拟。对吸附规律进行了探讨。结果表明,吸附效率随着震荡时间的延长pH的增大而升高。三种重金属离子在活性炭纤维上的吸附可用Langmuir和Freundich模式较好地描述。吸附形式呈单分子层且易于进行。结果表明,活性炭纤维对水中三种重金属离子的吸附特性良好,且吸附剂易于再生,可作为去除水中离子态重金属的优良吸附剂。Activated Carbon Fabric(ACF)was used as adsorbent of cadmium,nickel and copper in water in this paper.The effect of shaking time,ACF amount,and pH on the adsorption efficiency was investigated.The adsorption isotherm was represented,too.The results show that the adsorption efficiency increases with addition of shaking time,ACF amount and rise of pH.The adsorption of the three heavy metals cations onto ACF can be well described by Langmuir and Freundlich models.The adsorption appears monmolecular type and it is easy to be performed.The results also indicate that the performance fo the adsorption of the three cations on to ACF is good.The adsorbent is easy to be regenerated.So ACF can be used as fine adsorbent to remove heavy metals cations from water.
