Cr(III)-organic complexes removal from wastewater is challenging to decompose the complexes without producing toxic Cr(VI). Herein we demonstrated that oxalated zero-valent iron (Ox-ZVI) could one-step decomplex 95.4% of Cr(III)-EDTA with 94.2% removal of total Cr and 60.5% removal of TOC without generating Cr(VI) at pH 6.0. Ox-ZVI with FeC2O4 shell preferred to adsorb and activate O2 to produce more reactive species than ZVI with iron oxide shell, while the generated 1O2 could selectively break the Cr-O and Cr-N bond to precisely decomplex Cr(...
