ABSTRACT
In this study, cellulose acetate (CA) supported Ni/Fe nanoparticles were prepared and the ability of these nanoparticles to remove trichloroethylene (TCE) from water was studied. The effects of TCE reduction by the nanoparticles and sorption by the CA support were accounted for separately in the model. CA supported post-coated Ni/Fe nanoparticles were used to investigate the effect of metal particle composition on the observed reduction rate constant. The results show that the metal mass normalized observed reduction rate constant was proportional to the Ni content in the post-coated Ni/Fe nanoparticles in the range of 0-14.3 wt.%. This constant reached a maximum between 14.3 and 21.4 wt.% and decreased with further increase in Ni content. CA supported co-reduced Ni/Fe bimetallic nanoparticles gave poorer performance compared to CA supported post-coated Ni/Fe bimetallic nanoparticles at the same Ni content in Ni/Fe nanoparticles.
