Özet

The removal of chromium(VI) from aqueous solution under different conditions using an adsorbent was investigated. This adsorbent is Beech (Fagus orientalis L.) sawdust studied by using batch techniques. Batch studies indicated that the percent adsorption decreased with increasing initial concentration of chromium(VI). A contact time of 80 min was found to be optimum. Maximum chromium(VI) removal was observed near a pH of 1.0. Adsorption conformed to the Freundlich and Langmuir isotherms. (C) 2003 Elsevier Ltd. All rights reserved.
