Abstract:Lead contamination of water sources poses a serious risk to ecosystems and human health. We developed a silica-based biosorbent incorporating poly-tannic acid to efficiently remove Pb(II) ions from water. The laccase was immobilized on silica bead surfaces via an enzymatic process facilitated by a protective layer of silicatein. This approach prevents enzyme leaching, ensuring immobilized laccase stability under harsh conditions. Polytannic acid was formed on the bead surface through laccase-mediated polymeriz… 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.
