In　the　research,　sulfide　nanoscale　zero-valent　iron　(S-nZVI)　was　synthesized,　characterized　and　further　applied　to　remove　hexavalent　chromium　Cr(VI)　from　water.　The　results　showed　that　a　maximum　adsorption　(81　mg/g)　and　repeatability　was　reached　at　a　sulfur/iron　molar　ratio　of　0.1.　Sulfide　modification　could　form　amorphous　FeS　on　the　surface　of　nZVI,　which　enhanced　the　antioxidant　activity　and　hydrophobicity　of　S-nZVI0.1.　The　removal　of　Cr　(VI)　by　S-nZVI0.1　was　in　accordance　with　the　pseudo-second-order　and　Langmuir　model　with　the　theoretical　removal　capacity　of　83.51　mg/g.　After　aging　45　d,　60　mg/g　of　Cr(VI)　still　was　adsorbed　by　S-nZVI0.1,　suggesting　that　S-nZVI0.1　exhibited　a　better　stability.　84.1　%　of　Cr(VI)　was　reduced　to　Cr(III)　on　the　surface　of　S-nZVI0.1,　Fe0,　FeS,　Fe2+　and　S2-　were　involved　in　the　reduction　reaction.　This　study　provided　guidance　for　synthesizing　well　stability　and　high　reaction　of　S-nZVI　to　remove　Cr(VI).
