Batch Degradation of TCE The results of the batch degradation experiments by chitosan-embedded Ni/Fe nanopaiticles in Figure 8.10 show the simultaneous dechlorination of TCE and formation of ethane as the main product, consistent with the results obtained in the reported literature using colloidal bimetallic Ni/Fe nanoparticles (Schrick et al., 2004 Tee et al., 2005) and different systems of membrane-embedded Ni/Fe nanoparticles (Meyer et al., 2004 Xu et al., 2005).
