What is it about?
Low-cost adsorbents obtained from agricultural, biomass, and industrial residues and wastes can provide sustainable solution for treating wastewater. These adsorbents have required functionalities and characteristics, which allow the removal of harmful water pollutants from potable and wastewater, and at same time, these materials contribute toward minimization of wastes, their recovery, and reuse.

Why is it important?
Diverse inorganic contaminants such as toxic heavy metals, nitrites, phosphates, chlorides, and other impurities consisting of pesticides, pharmaceuticals, perchlorates, halogenated and phenolic compounds, endocrine disrupting compounds, inorganic acids, herbicides, fertilizers, and numerous other compounds have been found in various ground, surface, and wastewater throughout the world. So we need suitable and sustainable low cost materials (adsorbents) to remove these inorganic pollutants from water/waste water.
Perspectives
The presence of inorganic contaminants, even in trace amounts, are very threatening and hold humans, aquatic organisms, and flora and fauna vulnerable to various diseases and even death. The removal efficiency of these pollutants bank on the type of treatment method chosen, the concentration of impurities in water/wastewater, and environmental and geographical factors. this chapter discusses a plethora of natural and other low cost adsorbents with their material characteristics and useful applications.
