As a statistical approach, this study was focused on how feedstocks, pyrolysis temperature, production method and modification affect to the physiochemical properties of BC and how these properties affect to the adsorption of methylene blue (MB), crystal violet (CV) and rhodamine B (RB) from aqueous medium.enBiocharMethylene blueCrystal violetRhodamine BModificationsVan-Krevelen diagramsmeta- analysisArticle
