| description | In this paper, the micro powder was the product of cedar leaf (MPCL) is used as a low-cost and natural adsorbent for the removal of Co2+ from aqueous solutions. Factors such as the pH effect initial metal ion concentration, contact time, MPCL dosage and temperature on the adsorption performance of MPCL for Co2+ ions were experimented by batch method. Results indicate that removal of Co2+ ions at pH values of 7, the Langmuir isotherm model is the most suitable one for the adsorption process using MPCL (R2=0.9775), thus indicating the applicability of monolayer coverage of Co (II) ion on MPCL surface. The Relationship between Thermodynamic parameters was used to predict the absorption process. According to Thermodynamic analysis, the process exothermic and natural. |
