Abstract
Biochar, a naturally occurring and renewable carbon material, becomes porous through activation. Activated biochar is an ideal candidate for use as an adsorbent. The objective of this study is to investigate whether activated biochar derived from Colorado soft pine serves as a better adsorbent and demonstrates enhanced adsorption capabilities after undergoing secondary physical activation at various activation times. The effect of secondary action time on physical adsorption properties drawn from the analysis of isotherm plots, surface areas and pore size patterns were examined by using a physisorption analyzer. Chemical structures were identified using both ultimate and proximate analyses, while porosity was analyzed through the examination of SEM images. The results have been optimized and applied for the effectiveness of arsenic adsorption from synthetic storm water. It was found that increasing the secondary activation time enhances the activated biochar’s adsorption capacity and the secondary physical activation method is an efficient method to develop an effective adsorbent for removing arsenic in wastewater treatment.
