摘要
对活性碳纤维(ACF)吸附水溶液中的二价铅离子进行研究。分别运用静态和动态方法来考察 ACF吸附 Pb2+ 的性能,测定了吸附等温线,探讨了吸附时间、pH 值等因素对吸附的影响,并进行了 ACF 的再生实验。结果表明,ACF 对水中二价铅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。
The adsorption of Pb2+ on activated carbon fiber ( ACF ) from aqueous solution was investigated. Adsorption isotherm and dynamic adsorption breakthrough curve were determined through static and dynamic adsorption, respectively. The influence of pH value and adsorption time on the adsorption was studied. The results indicated that ACF is good adsorbent for Pb 2+remo val from aqueous solution. Besides, ACF used is easy to be regenerated. So ACF could be used as an efficient adsorbent for Pb2+removal from water.
