The　ferrite　process　has　been　developed　to　purify　wastewater　containing　heavy　metal　ions　and　recycle　valuable　metals　by　forming　chromium　ferrite.　However,　organic　matter　has　an　important　influence　on　the　crystallization　behavior　and　stability　of　chromite　synthesized　from　chromium-containing　wastewater.　We　focused　on　the　influence　and　effect　mechanism　of　two　typical　organic　acid　salts　(citrate　(CA)　and　tartrate　(TA))　on　the　process　of　chromium　mineralization.　It　was　found　that　the　presence　of　organic　matter　leads　to　the　increase　of　the　residual　content　of　Cr　in　CA　system　(0.50　mmol/L)　and　TA　system　(0.61　mmol/L)　in　the　solution,　and　the　removal　of　chromium　was　mainly　due　to　the　surface　adsorption　of　Fe(III)　hydrolysate.　The　decreased　crystallinity　of　mineralized　products　is　ascribed　to　the　completion　of　organic　compounds　with　Fe(II)　and　Fe(III),　which　hinders　the　formation　of　ferrite　precursors.　There　was　bidentate　and　monodentate　chelation　between　-COO-　and　metal　ions　in　the　CA　system　and　TA　system　respectively,　which　resulted　in　a　stronger　affinity　between　CA　and　iron.　This　study　provides　the　underlying　mechanism　for　Cr(III)　solid　oxidation　by　the　ferrite　method　in　an　organic　matter　environment　and　is　of　great　significance　to　prevent　and　control　chromium　pollution　in　the　environment.　©　2022　Elsevier　B.V.
