Activated Carbons from lignocellulosic waste materials for water treatment: a review
Activated Carbon (AC) adsorbents are commonly used to remove pollutants from water because of their excellent sorption ability. However, commercially available ACs are expensive. In developing countries where economy plays a very big role, it is better to find low-cost locally available precursors, which are renewable resources for the preparation of ACs. This review focuses on ACs prepared from agricultural wastes. The textural, chemical, physical and adsorptive properties of ACs prepared from each source are assessed.
