Adsorption of pb~(2+) by ACF from aqueous solution

LI Qiu-y

Abstract

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.
