Efficient removal of Cr(VI) at alkaline pHs by sulfite/iodide/UV: Mechanism and modeling

•Efficient removal of Cr(Ⅵ) at alkaline pHs was obtained in sulfite/iodide/UV.•The process was effective in real surface water and industrial wastewater.•Roles of sulfite and iodide were quantified, and the synergy was interpreted.•Mechanism of Cr(VI) removal was revealed, and pathways were proposed...
