dc.description.abstractThe objective of this work is to study the adsorption of methylene blue (MB) dye solution using magnesium zinc ferrite nanoparticles (MZ NPs) synthesized by combustion method. Polyethylene glycol (PEG), urea and oxalyl dihydrazide (ODH) were used as fuel for synthesis and metal nitrates were used as oxidizers. The synthesized MZ NPs were characterized by FT-IR, XRD, VSM, SEM-EDS and TEM analysis. SEM images showed particle agglomeration. XRD confirmed formation of spinel MZ NPs. TEM images taken by water dispersion method clearly depict ultra-fine, well dispersed spherical MZ NPs. Batch adsorption studies were carried out and the effect of experimental parameters like - pH, amount of adsorbents, contact time and temperature were studied. The maximum adsorption of MB was achieved at pH 10. Percentage removal of MB increased with increase in adsorbent dose. ΔHo was reported to be positive for MZ NPs which confirmed endothermic nature of adsorption. Langmuir and Freundlich isotherms fit the data better than D-R isotherms. The trend for the percentage removal of MB dye by MZ NPs and activated charcoal in the ascending order was PEG < ODH < Urea < Charcoal. The advantage of MZ NPs over activated charcoal is their role as photocatalyst for degradation of dyeen_US
