Removal of hexavalent chromium from aqueous by Chitosan-stabilized FeS
Water-Energy Nexus, 2023 In this study, FeS and chitosan (CTS) were compounded to form a new Cr (Ⅵ) treatment material FeS/CTS. FeS/CTS was characterized by SEM, FTIR, XRD, XPS, BET, etc, and the removal performance and mechanism of FeS/CTS for Cr (Ⅵ) were also discussed.

Cr(Ⅵ) reduction in aqueous solutions by limonite(褐铁矿处理水中六价铬)
Zhejiang Daxue xuebao. Lixue ban, 2008 Cr(VI)是土壤和水体中常见的有毒污染物，将Cr（VI）转化为毒性较低的Cr（Ⅲ)是常用而有效的治理方法.本文采用褐铁矿对水中Cr(Ⅵ)进行处理研究，考察了褐铁矿投加量、Cr（Ⅵ)初始浓度、pH值、反应温度、铁矿石粒径大小以及添加不同物质等因素对褐铁矿去除效果的影响.结果表明，褐铁矿对Cr(Ⅵ)有很好的还原去除效果，Cr(Ⅵ)去除效率随褐铁矿用量的增加而增大，随Cr(Ⅵ)初始浓度的增加而减小，pH值越低越有利于反应的进行.铁矿石颗粒的直径越小，比表面积越大，也对反应越有利，而温度对Cr(Ⅵ ...
