| Summary: | This study explored the low-cost adsorbent of durian peel for BPA removal from aqueous solutions. The effect of various operational parameters such as contact time, temperature, concentration, agitation and pH on the adsorption of BPA was investigated using the batch adsorption study. It was found that Durian peel can be used as a low cost adsorbent for the removal of BPA in aqueous solution after treated with sulfuric acid. The effects of morphology, functional groups, and surface area of adsorbent, before and after pretreatment with sulfuric acid and reaction were investigated by using FESEM, FTIR, and BET. The present study indicates that durian peel had removed 69.63% of BPA with adsorption capacity of 4.178 mg/g for 24 hours. The result proved that this treated agricultural waste was promising material as an alternative adsorbent for the removal of BPA from aqueous solution. Kinetic study of the results gave a pseudo-second order type of mechanism while the adsorption characteristics of the adsorbent followed the Langmuir adsorption isotherm. |
