Engineered biochar from wood apple shell waste for high-efficient removal of toxic phenolic compounds in wastewater

Abstract This study investigated a novel agricultural low-cost bio-waste biochar derived from wood apple fruit shell waste via the pyrolysis method, which is modified by ball milling and utilized to remove toxic phenol and chlorophenols (4-CPh and 2,4-DCPh) from contaminated aqueous media. The ball-...
