Abstract:Abstract.This paper demonstrates a simple environment-friendly synthesis route of iron oxide yellow (Į-FeOOH) using spent pickling solutions as raw material. After abundant laboratory experiments, we finally pinned down the best procedure. The research showed that Į-FeOOH nanometer material with average diameter of 50nm and average length of 400 nm was prepared at the optimal technique. And the FeOOH content of the sample was as high as 90%, which is higher than the 86% of GB/T1863-2008. The structure, morphol… 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.
