Abstract:For the first time, an industrial solid waste (CAS) was used for the rapid oxidation and neutralization of acidic sulfate soil. The waste mainly contained Fe-doped CaCO 3 and CaAl-layered double hydroxide (LDH). After treatment, CAS neutralized the acidic soil with the aid of hydrogen peroxide. Compared with other oxidationaccelerating materials, including activated carbon, biochar, and Fe-doped biochar, CAS showed the best oxidation rate acceleration. When the ratio of CAS and sulfur in acidic soil was 1.5:1,… 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.
