Preparation And Characterization Of Activated Carbon From Oil Palm Trunk Fiber By Chemical Activation

Industrial activated carbon has been a favoured adsorbent for the removal of a variety of contaminants, but its relatively expensive cost has limited its broad application. As the commercial activated carbon produced from non-renewable and unsustainable resources, this situation led to study on the...

description Industrial activated carbon has been a favoured adsorbent for the removal of a variety of contaminants, but its relatively expensive cost has limited its broad application. As the commercial activated carbon produced from non-renewable and unsustainable resources, this situation led to study on the possible alternative and low-cost replacements on raw materials to produce activated carbon. Due to the extensive discharge of pollutants, activated carbon produced from biomass waste by various processing methods and conditions is gaining popularity as a promising adsorbent for ecological treatment. Methods of manufacturing activated carbon, the type of lignocellulosic biomass waste, and the interaction between adsorbent and adsorbate are essential elements that must be considered in order to develop an effective adsorbent. Oil Palm trunk fibre (OPTF) is one of the major oil palm biomass wastes with a high carbon content that can be used as a precursor to produce activated carbon (AC) by utilising phosphoric acid (H3PO4) that can be turned into activated carbon with a large surface area and porous structure.
