摘要：
The ability of "waste" red mud to adsorb 2-chlorophenol was investigated. Effects of contact time, initial concentration, pH. adsorbant dose and agitation speed on adsorption capacity and desorption were studied. The adsorption kinetics followed the first order rate expression. Adsorption followed Freundlich isotherm. A maximum removal of 83% was observed at pH 8.00. Desorption of phenol from the spent adsorbent with water at pH 11.0 was only 41%, indicating that both physisorption and chemisorption occur in the adsorption process.
