An efficient and robust flow-through electrochemical Ti4O7 membrane system for simultaneous Cr(VI) reduction and Cr immobilization with membrane cleaning by a periodic polarity reversal strategy

A novel sludge-based biochar composite adsorbent CS/SBC-H3PO4 for efficient Cr(vi) removal from aqueous solution

“…1 Compared with Cr( iii ), Cr( vi ) is highly toxic and mobile, and it can cause great harm to organisms and ecosystems. 2 The removal methods of Cr( vi ) include adsorption, 3 membrane separation, 4 chemical precipitation, 5 ion exchange 6 and bioremediation. 7 Among these, the adsorption method has widely attracted attention from researchers for its advantages of high efficiency, simplicity, and low cost.…”
