摘要：

Iron/nickel　(Fe/Ni)nanoparticles　prepared　by　liquid-phase　reduction　were　deposited　onto　the　surface　of　modified　zeolite　to　obtain　a　supported　composite　material.　The　Fe/Ni　nanoparticles　were　well-dispersed　on　the　surface　of　the　modified　zeolite.　The　removal　path　of　2,4-dichlorophenol　(2,4-DCP)　by　the　composite　material　includes　adsorption　and　degradation,　with　the　latter　being　the　primary　process.　The　experimental　results　show　that　nearly　80%　of　2,4-DCP　was　removed　under　the　following　reaction　conditions:　initial　2,4-DCP　concentration,　20　mg·L-1;　composite　material　dosage,　6　g·L-1;　and　reaction　temperature,　25℃.　The　removal　of　2,4-DCP　by　the　composite　material　is　significantly　different　under　alkaline　conditions　but　not　acidic　conditions.　The　degradation　product　of　2,4-DCP,　phenol,　was　adsorbed　on　the　surface　of　the　material,　avoiding　secondary　pollution　of　the　water　environment.　©　2017,　Science　Press.　All　right　reserved.
