The Potential of Agricultural Waste Chars as Low-Cost Adsorbents for Heavy Metal Removal From Water

Abstract

Ensuring that every human being has access to clean and safe drinking water is a major global concern. The challenge of heavy metal contamination in water poses a serious risk to human health. This chapter aims to explore an eco-friendly and cost-effective solution to address water contamination issues. The focus is on using pyrolysis char derived from agricultural waste as a low-cost adsorbent to efficiently remove heavy metals from water. A thorough review of relevant literature, emphasising the advantages of pyrolysis char and highlighting recent advancements in the field, is performed. Additionally, an outline of potential challenges and future research direction in this promising area is given.
