ABSTRACT

Decontamination of toxic pollutants from aqueous solutions is mandatory owing to the deleterious effects they render to the environment. Biosorption is a capable and effective process shown to be more promising than conventional processes like flocculation, sedimentation, coagulation, and filtration. Plant-derived biomasses are natural, eco-friendly nontoxic options utilized in their native form as biosorbents owing to their structural and functional properties suitable for contaminant sequestration. This chapter is brief on the advantages of biosorption and the characteristics of biomass as biosorbents. Also, the parameters to be controlled for maximum adsorption capacity have also been discussed. Characterization procedures for analyzing the biosorbents were also enumerated. This would be useful in understanding the basic knowledge about biosorption and its advantages in removing toxic pollutants from water systems.
