Abstract:This research exploited biochar, sourced from Ginkgo leaves (GLs), to facilitate the adsorption of 2,4‐dichlorophenoxyacetic acid (2,4‐D) in aqueous environments. The results reveal that GL biochar, activated with ZnCl2 at a temperature of 500°C (500‐ZGBC), demonstrated the greatest specific surface area (SBET) of 536.0 m2 g−1 for 2,4‐D adsorption. The biochar's properties, including specific surface area, morphology, structure, thermal stability, and functional groups, were analyzed. Additionally, studies of … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
