Abstract
Heavy metals are threatening to human health as they are arduous to remove from water bodies. Many technologies like photocatalysis, reverse osmosis, precipitation, and adsorption are used to get rid of those heavy metals from water. Among all these methods, adsorption is one of the most efficient methods to remove those heavy metals. In this chapter, the adsorption of heavy metals by dead biomass like algae, fungi, bacteria, and other biomass from waste will be discussed elaborately. The mechanisms of adsorption by these biomasses will be discussed, and the factors affecting their adsorption efficiencies are also included. The newest approach and emerging techniques are also considered. The future aspects and limitations are also considered.
