摘要：

To　enhance　the　dispersivity　of　nano　zero-valent　iron　(NZVI)　used　for　removing　2,4-DCP　from　water,　the　surfaces　of　NZVI　was　modified　with　F-127　as　an　environmentally　friendly　organic　stabilizer.　Based　on　different　mass　ratio　of　F-NZVI　particles　sedimentation　experiment　and　2,4-DCP　removal　experiment,two-stage　process　(sedimentation　removal　and　suspension　removal)　was　found.　The　optimum　mass　ratio　of　F-127　to　NZVI　particles　was　found　to　be　2:1　and　the　maximum　removal　efficiency　was　72.32%.　The　surface　morphology,　composition　and　crystal　structure　of　the　samples　were　analysed　by　using　scanning　electron　microscope　(SEM),　Fourier　Transform　Infrared　Spectroscopy　(FTIR),　X-Ray　Diffraction　(XRD)　and　X-ray　photoelectron　spectroscopy　(XPS),　respectively.　Results　show　that　F-127　significantly　improved　NZVI　dispersibility　and　oxidation　resistance.　Final,the　main　factors　of　F-NZVI　for　the　removal　2,4-DCP　in　water　were　studied　to　find　the　optimal　2,4-DCP　removal　condition,　which　were　pH=5,　3　g•L-1　F-NZVI　for　20　mg•L-1　of　2,4-DCP.　©　2019,　Science　Press.　All　right　reserved.
