Abstract

Activated carbon prepared from Ricinus communis pericarp (RCP) was used to remove Fe(II) ions from aqueous solutions by adsorption technique under varying conditions of agitation time, metal ion concentration, adsorbent dosage, pH and desorption. The effective pH was found to be 5 ± 0.2. Adsorption followed both Langmuir and Freundlich isotherm models.
