摘要：

Sorption of Zn2+ from aqueous solutions by fly ash, clay and bentonite was investigated. The results of kinetic experiments showed that the sorption process of Zn2+ was rapid. The sorption data showed that sorption capacity of Zn2+ by fly ash and bentonite was much larger than those by clay and silty clay; and the sorption capacity of Zn2+ by fly ash was equal to that by bentonite. Equilibrium modeling of sorption showed that at high concentration, the sorption of Zn2+ by fly ash, clay and silty clay were fitted to a Langmuir isotherm. The results also showed that when Zn2+ loading in adsorbents increased, the percentage of Zn2+ sorption by adsorbents such as fly ash decreased.
