    Abstract

    This article reports the development and biosorption properties of iron oxide magnetic nanoparticles incorporated Gum ghatti based nanocomposites for the remediation of methylene blue contaminated water. The physico-chemical and structural characterization confirmed the incorporation of Fe3O4 MNPs with in the polymer matrix. Adsorption kinetics followed pseudo second order rate model. Adsorption isotherm fitted well with the Langmuir adsorption isotherm with the maximum adsorption capacity of 671.14mg/g. Thermodynamic parameters like δS0, δH0 and δG0 were investigated and the desorption studies showed that the nanocomposite can be regenerated and reused for the removal of methylene blue.
