“…The keywords used to search for literature on the databases are as follows: biochar, cellulose, lignin, pyrolysis, and carbonization associated with the feedstocks and biochar production methods; industrial, agricultural, pharmaceutical, heavy metals, dyes, pesticides, antibiotics, and persistent contaminants reflecting biochar application; electrostatic interaction, precipitation, complexation, hydrophobic effect, and chemical bonds referred to sorption mechanisms; porosity, surface area, functional groups, magnetization, and biochar-based composites related to modification methods. Besides, literature research was specially conducted within the papers on ''Special Issue on Biochar: Production, Characterization and Applications -Beyond Soil Applications'' published on ''Bioresource Technology,'' and papers published on ''Journal of Chemical Technology and Biotechnology,'' which were presented in the 2017 European Geosciences Union session ''Novel Sorbents for Environmental Remediation'' (Sanroman et al, 2017;Manariotis, Karapanagioti & Werner, 2017).…”
