Abstract:Biomass is a source of low-cost adsorbents used in the removal of contaminants. In this study, shells from an indigenous tree in Southern Africa called Morula were pyrolyzed to produce biochar that was used to sequester heavy metals from coal wash water. The produced biochar was activated using hydrochloric acid (HCl) and parameters such as the cation exchange capacity (CEC), point of zero charge (pHzc), elemental composition, mineral composition, proximate analysis and surface functional groups were determine… Show more
