For the first time Fe/Ni-D072 composite was used to dechlorinate TCE. The effects of various factors on the TCE removal efficiency were investigated. The stability and durability of Fe/Ni-D072 was examined. Fe/Ni-D072 can be a promising catalyst for removing TCE. a r t i c l e i n f o a b s t r a c t Article history: In this study, Fe, Ni, and Fe/Ni nanoparticles were successfully incorporated in commercial polystyrene Received 11 February 2015 cation exchange resin, D072, to form Fe-D072, Ni-D072, and Fe/Ni-D072 composites.
