Bio-based Methods for Wastewater Treatment: Green Sorbents

What is it about?

Due to their high cost and environmental impact, conventional treatment methodology of heavy metals polluted waters usually did not receive public acceptance. Recently, phytoremediation is considered as a cheaper and eco-friendly alternative treatment method. Phytoremediation includes two uptake processes: biosorption and bioaccumulation. This chapter elaborates the advantages and disadvantages of these two processes. A brief description of different environmental factors affecting biosorption isotherm, equilibrium, and kinetic models are also provided. Moreover, factors affecting biosorption process are discussed and the merit of using factorial experimental design in the optimization of biosorption process and reducing the number of experimental runs were also highlighted. A brief account of quality control and assurance for biosorption experiments are provided.
