Removal of Hexavalent Chromium in Aqueous Solution by Cellulose Filter Paper Loaded with Nano-Zero-Valent Iron: Performance Investigation and Numerical Modeling
Abstract:Cr(VI) pollution in water bodies is very harmful to human health and the environment. Therefore, it is necessary to remove Cr(VI) from water. In this study, the composite (FP-nZVI) was prepared by loading nano-zero-valent iron (nZVI) onto cellulose filter paper (FP) using a liquid-phase reduction method to improve the dispersibility and oxidation resistance of nZVI. In batch experiments, the effects of iron loading of FP-nZVI, initial concentration of Cr(VI), temperature, and pH on Cr(VI) removal were particul… Show more
“…57 Rice straw-derived hydrothermal carbon and cellulose lter paper have been used as support for nZVI, aiming to improve the dispersibility and oxidation resistance of nZVI during the reduction of Cr(VI). 100,101 Most of the Cr can be recovered from water utilizing the magnetically separating of nZVI material. While the cover of precipitate may reduce the activity of nZVI.…”
