Abstract

Over the years, numerous industrial activities have proved to be highly detrimental to the environment. Various pollutants have health impacts such as endocrine disruption and chronic kidney and liver diseases. Therefore, there is an urgent necessity to develop new and efficient methods to eliminate contaminants from water resources. The advantages associated with agricultural waste include a wide array of sources, cost-efficiency, high flexibility, and renewability. The lucrative structural features being loose and porous and presence of functional groups such as the carboxyl group and hydroxyl group make agricultural waste a potential biological adsorbent for pollutant management. It needs to be focused that the majority of agricultural wastes are not often utilized in their original state, rather tailored in different ways to enhance the material’s surface area for adsorption and porosity. Carbonization, thermal treatment, physical and chemical activation, grafting with co-polymers, nanostructuring, and many others are few of the generally used methodologies that are recently being utilized to modify agricultural waste materials for use as adsorbents. This chapter aims to provide key insights on the technical realizations in the area of adsorption by using agricultural wastes as precursor materials for preparing adsorbents. Moreover, it points out the adsorption mechanism and at the same time gives the future development prospect of agricultural waste as adsorbent.
