Abstract:The current disposal of waterworks sludge (WS) by landfill or discharge into water body results in land consumption and environment pollution. To solve the problem, alum-based waterworks sludge (AWS) was reclaimed and reused to develop adsorbent for aqueous tetracycline hydrochloride (TCH) removal. WS was modified using HCl solution and Fe 2+ /Fe 3+ coprecipitation to get acidized and magnetized waterworks sludge (Fe 3 O 4 @HAWS) for the improvement of its adsorption capacity and separation efficiency. Fe 3 O … 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.
