Supported Iron

A new class of nanoscale zero-valent iron particles supported on natural montmorillonite and organo-montmorillonite were synthesized and the feasibility for the removal of and was examined through laboratory batch test. The X – ray diffraction (XRD) and Fourier Transform Infrared spectrum (FTIR) investigation has been applied for determination of the particle size and mechanism of remediation process. The aim of this study was to enhance the reduction of persistent environmental pollutants difficult to degrade by immobilization of nanoscale zero-valent iron on an organo-montmorillonite. Batch experiments indicated that the reduction of both and was much greater with organo-montmorillonite supported iron nanoparticles reaching removal rate up to 98.5% and 95.6% respectively at the initial metal concentrations of 50 mg/L. Iron and crystalline iron oxide were detected by X-ray diffraction patterns. In the FTIR spectrum, CH2 groups were found in iron nanoparticles supported on hexadecyltrimethylammonium bromide modified montmorillonite (HDTMA-Mont/nZVI) particles but were significantly weakened in comparison with the spectrum of hexadecyl trimethylammonium bromide (HDTMA). Other factor that affects the efficiency of heavy metals removal such as pH values was also investigated. The obtained data and review of the current literature have given the opportunity to figure out the mechanisms of and removal which may thus promote the industrial application of nZVI technique in environmental remediation by changing the hydrophilic – hydrophobic properties of source systems.

Two kinds of supported iron nanoparticles by activated carbon/carbon nanotubes were synthesized under ambient condition in this study. And their performance for pentachlorophenol (PCP) removal in water was examined. The SEM images showed that the nanoparticles supported by carbon nanotubes (Fe-CNTs) were of better dispersibility and smaller particle size than that by activated carbon (Fe-C). And the iron content in both of Fe-CNTs and Fe-C system measured by EDS was similar to each other. But the removal rate of PCP in the former system was obviously lower than the latter. It might be due to the more excellent adsorption capacity of activated carbon. And another main reason could be the reduction of adsorption sites due to the occupation of iron nanoparticles. The removal of PCP from the solution was the result of both of the activated carbon/carbon nanotubes adsorption and iron degradation. And the adsorption process was prior to the degradation by iron nanoparticles.
