2,4-Dichlorophenol　(2,4-DCP)　has　been　extensively　applied　for　chemical　and　pharmaceutical　production,　resulting　in　severe　environmental　pollution.　In　this　paper,　the　sulfided　nanometer　zero-valent　iron　(S-nZVI)　was　synthesized　and　applied　to　remove　2,4-DCP.　The　experimental　tests　displayed　that　when　the　sulfur　iron　mole　ratio　was　0.129,　the　elimination　rate　for　2.4-DCP　was　91.9%,　and　the　removal　rate　declined　when　the　sulfur-to-iron　proportion　increased.　As　the　initial　concentration　of　2,　4-DCP　improved　from　10　to　40mgL-1,　the　elimination　rate　of　2,4-DCP　declined　from　92.6%　to　65.3%.　The　elimination　effect　of　S-nZVI　on　2,4-DCP　increased　with　rising　temperature.　The　removal　rate　of　2,4-DCP　varied　under　various　pH　conditions.　The　removal　efficiencies　were　reduced　from　75.5%　to　48.8%　when　the　initial　pH　ranged　from　5　to　3.　When　pH　is　11,　the　removal　rate　is　97.9%.　Kinetics　of　degradation　reaction　of　2,4-DCP　under　different　conditions　were　conducted.　The　process　for　removing　2,4-DCP　was　in　accord　with　the　pseudo-first-order　kinetics　model.　The　initial　pH　and　sulfur　mole　ratio　played　a　decisive　role,　which　determined　the　removing　rate　of　2,4-DCP.　The　findings　can　guide　more　efficient　S-nZVI　reactivity　towards　the　target　contaminants　in　water　remediation.　©　The　Authors,　published　by　EDP　Sciences.
