In the proposed study, biochar will be produced from selected vegetable waste (spent coffee grounds and tea leaf residue) through pyrolysis. The sorption mechanisms (adsorption and desorption) of the persistent toxic substances (PTS) mixture, including arsenic (As), zinc (Zn), lead (Pb), mercury (Hg) (total and methylmercury (MeHg)), dichlorodiphenytrichloroethane (DDT), phthalates esters (PAEs), perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) by different size of vegetable-based biochar will be investigated.
