A Guide to Biochar for Water Treatment: From Nature Clean

This book provides a comprehensive overview of biochar as a sustainable and efficient adsorbent for water treatment. It covers the entire lifecycle of biochar-from feedstock selection and thermochemical production (pyrolysis, gasification, hydrothermal carbonization) through various physical and chemical modifications designed to enhance adsorption performance. Key physicochemical properties (surface area, porosity, functional groups, crystalline structure, morphology) are discussed in relation to pollutant removal mechanisms, including physisorption, chemisorption, ion exchange, electrostatic attraction, and ¿-¿ interactions. The application of biochar for removing heavy metals (Pb²¿, Cd²¿, Cu²¿, Cr¿¿, Hg²¿), dyes (methylene blue, crystal violet, malachite green), pharmaceuticals (ibuprofen, tetracycline, diclofenac), and other emerging contaminants (pesticides, phenols, PFAS) is systematically evaluated through batch and fixed-bed column studies. The influence of operational parameters (pH, dosage, contact time, initial concentration, temperature) on adsorption efficiency is analyzed.
