Synthesis of Iron Oxide Yellow from Spent Pickling Solutions
Department of Chemistry, School of Science, Tianjin University, Tianjin, China
This paper demonstrates a simple environment-friendly synthesis route of iron oxide yellow (α-FeOOH) using spent pickling solutions as raw material. After abundant laboratory experiments, we finally pinned down the best procedure. The research showed that α-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, morphology and size distribution of the product was characterized by X-ray diffraction (XRD), Transmission electron microscope (TEM), Scanning electron microscope (SEM) and Malvern lazer particle analyzer, respectively. The test results show that all the indices of as-prepared iron oxide yellow are completely in conformity with and even better than national primes standard.
