Process Optimization of Zinc Removal Using Microwave Incinerated Sugarcane Bagasse Ash (MISCBA) Through Response Surface Methodology

並列摘要


Microwave Incinerated Sugarcane Bagasse Ash (MISCBA) was used in the exclusion of zinc from aqueous solution. Parameters of importance like initial metal concentration, adsorbent dosage and agitation time were examined to find their effect on the adsorption process. Respond surface methodology has been employed to enhance the process conditions based on Box-Behnken design. Response surface method suggest initial metal concentration of 50 mg/L, adsorbent dosage 1.0 g and contact time of 3 h with removal efficiency of 55.99% to be optimum conditions for zinc removal from aqueous solution. A high correlation coefficient of 0.9923 indicates the model is in agreement with the experimental values. The model indicates that adsorbent dosage is the major influencing factor among others responsible for the adsorption of zinc.
