In present study, Meldrum’s acid modified magnetite nanoparticles (MA-Fe3O4) were synthesized for the removal of methylene blue byco-precipitation method. These coated nanoparticles were examined by TGA, FESEM, XRD, FTIR and UV-vis analysis. The FESEMresults depicted that mean size of modified superparamagnetic iron oxide nanoparticles (SPIONs) was about 30 nm. Meldrum’s acidmodified magnetic nanoparticles were found extremely effective in methylene blue dye adsorption from aqueous solution. The dataobtained from isotherm study showed that adsorption process was consistent with Freundlich Model. Moreover, kinetic studies revealedthat the adsorption of the dye on surface of coated magnetic nanoparticles followed pseudo-second order kinetics. Additionally, a comparativestudy has been made for the methylene blue dye removal efficiency by Meldrum’s acid modified magnetic nanoparticles with alreadyreported adsorbents.
