Adsorptive removal of antibiotics from water and wastewater: Progress and challenges. (2015, background): “In most cases, BC does not require additional activation process like AC for the removal of antibiotics although some researchers (Azargohar and Dalai, 2008; Uchimiya et al., 2012) have performed BC activation using different activating materials.”
Biochar-based materials and their applications in removal of organic contaminants from wastewater: state-of-the-art review (2019, background): “noted that KOH-treated BC exhibited higher BET surface area (783 m2/g) than the raw BC (less than 10 m2/g) (Azargohar and Dalai 2008).”
A novel method to tailor the porous structure of KOH-activated biochar and its application in capacitive deionization and energy storage. (2016, background): “Typically, high surface areas of chemically activated samples with KOH is attributed to their microporous structure [5,13,35,36].”
Characterization of biochar from fast pyrolysis and gasification systems (2009, background): “Combusting the char to supply process heat is common [3, 4], while a few chars may be suitable for further activation to be used in higher-value adsorption applications [5, 6].”
