摘要：

In this study the sorption of phenol and 4-chlorophenol on pumice modified with the cationic surfactants hexadecyltrimethyl ammonium bromide (HDTMA) and benzyldimethyl tetradecylammonium chloride (BDTDA) was investigated. Experimental studies indicate that HDTMA-pumice and BDTDA-pumice have the capability to remove phenol and 4-chlorophenol from aqueous solution. The influence of initial concentration and adsorbent dosage was studied. The adsorption of phenol and 4-chlorophenol increased with increasing initial concentration and decreased with increasing amount of adsorbent used. The Freundlich adsorption isotherm was found to describe well the equilibrium adsorption data. The parameters of the Freundlich model have been determined using the adsorption data.
