Degradation of DCE and TCE by FeaNi nanoparticles immobilised polysulphone matrix

The reduction of dichloroethane (DCE) and trichloroethylene (TCE) by bimetallic ironanickel (FeaNi) nanoparticles has been studied in this study. The reduction mechanism involves hydrodechlorination at the ironanickel interface. The FeaNi nanoparticles have been synthesised by the chemical reduction method and immobilised on to a polysulphone matrix. The as-synthesised nanoparticles and FeaNi immobilied polysulphone support have been characterised to establish the particle size of the nanoparticles, which are of the order of 36a41anm, and the physical characteristics of the immobilised support. Batch experiments have been performed using gas chromatography-mass spectrometry to study the degradation of DCE and TCE. The studies have shown that the bimetallic system is quite effective in the dechlorination of DCE and TCE. Also, the stability of the nanoparticles in the matrix has been explored with respect to its suitability for use in the degradation of chlorinated hydrocarbons.
