A novel magnetically separable adsorbent, namely magnetic γ-Fe 2O 3/crosslinked chitosan composites (Mγ-Fe 2O 3/CSCs), was prepared by miroemulsion process and characterized by XRD, FT-IR, TGA, DSC, SEM and VSM. Adsorption of methyl orange (MO), used as a model pollutant, from ...
The techniques employed were XRD, nitrogen adsorption at 196 °C and catalytic conversion of ethanol and isopropanol at 250–400 °C using micropulse technique. The results showed that the supported solids being calcined at 400 °C consisted of well crystallized CuO, NiO, Fe 2 O 3 and AlOOH...
Characterisation was done by XRD, FTIR and Raman spectroscopy. TEM showed that the average particle size of the two samples were 9 nm and 6 nm with a small particle size distribution. FTIR and TG showed that the -Fe 2 O 3 particles were capped with the diol. Mssbauer spectra of the 6...
