Abstract：

Encapsulated　nanoscale　zero-valent　iron　(En-nZVI)　particles　were　prepared　by　using　methyl　methacrylate　(MMA)　as　monomer　and　azobisisobutyronitrile　(AIBN)　as　initiator　to　embed　the　nanoscale　zero-valent　iron　particles.　The　characteristics　of　En-nZVI　particles　were　investigated　by　XRD,　FI-IR　and　TEM　analysis.　The　results　showed　that　the　En-nZVI　particles　with　the　PMMA　stable　layer　wrapped　outside　was　formed　by　in-situ　polymerization.　The　obtained　En-nZVI　particles　were　uniform,　disperse　and　stable　in　the　air　in　3　days　with　slow　oxidation.　Better　degradation　and　higher　dechlorination　of　TCE　by　En-nZVI　particles　could　be　achieved,　and　the　degradation　and　dechlorination　rates　could　reach　92%　and　90%　after　24h　reaction,　respectively.　©,　2014,　Science　Press.　All　right　reserved.
