Abstract
The treatment of heavy-metal-bearing wastewaters is a critical environmental challenge, as access to clean drinking water becomes increasingly difficult due to pollution and rising water treatment costs. Traditional adsorbents derived from fossil fuels are not sustainable and can contribute to secondary pollution. To address this issue, researchers have turned to biogenic sorbents made from modern biomass as a promising alternative. These biosorbents utilize biological waste materials that would otherwise contaminate water systems, promoting a circular economy and sustainable water treatment practices. This chapter explores the potential of biogenic sorbents for water decontamination, focusing on their use in the removal of heavy metals from contaminated waters. Further, this chapter delves into the preparation methods, adsorbent types, adsorption mechanisms, and regeneration techniques employed with these biosorbents.
