Study on Removal of p-Chlorophenol from Waste Water by Adsorption on Activated Carbon Fibers and Regeneration of the Adsorbent

Fan Jun

Abstract

The experiment that activated carbon fiber (ACF) was used to treat p-chlorophenol (PCP) waste water was studied. Adsorption isotherm and dynamic adsorption breakthrough curve were determined. The effects of temperature, flow rate ,the bed length on adsorption efficiency were studied. The result indicated that the adsorption capacity of ACF for PCP was favorable and the adsorption velocity was fast. The adsorption isotherm data can be represented by Langmuir isothermal. ACF regenerated by NaOH had not much difference in adsorption capacity.
