Hydrochar (HC), biochar (BC), and hydrochar-derived pyrolysis char (HDPC) are synthesized hydrothermally from the waste and then functionalized with TiO2(B), named as 'Composite-1', 'Composite-2', and 'Composite-3', respectively.  Adsorption kinetics and isotherms of TC removal are studied, while TC adsorption mechanisms are elaborated.
