Adsorption of Copper(II) Ion by Palm Oil Sludge Biochar Prepared by Pyrolysis: Equilibrium and Kinetics Studies

Annually, million tons of Palm Oil Sludge (POS) were produced from palm oil mill industries as side-product. Thus, it is very crucial to utilize POS for more advantageous purposes, especially in the circumstances of low-cost adsorbent development. Throughout this study, POS has been utilized for the...
