Application of Clay-Biochar Composites as Adsorbents for Water Treatment

Recently, biochar has been recommended as a supporting material for nanometric particles to prevent agglomeration and improve surface area. Among the conceivable uses, clay dispersion over biochar appears to be an intriguing and creative choice that allows for the simultaneous and synergistic exploitation of the adsorptionAdsorption capabilities of both materials. In fact, modifying biochar with clays to generate composites is projected to considerably increase its adsorptive activity, representing an important opportunity to broaden the uses of a sustainable low-cost adsorbentAdsorbents. In light of this, the purpose of this chapter is to investigate the adsorptionAdsorption of various contaminants on clays supported on biochar. The chapter will be divided into sections that cover the principles of clays, biochar, and their unique features, the main techniques of composite synthesis, and the use of these materials as adsorbentsAdsorbents for various contaminants.
