Abstract

In this article, the Methylene Blue dye adsorption is studied using NiFe2O4-Graphene Oxide composite as adsorbent. The NiFe2O4-graphene oxide (NiFe2O4-GO) nano-composite made by single step solvothermal approach. The characterization study revealed the abundance of functional group and nanomaterial features in prepared material. The MB adsorption is increased with rising adsorbent doses, pH, temperature and initial MB solution concentrations. Pseudo second order kinetic model got fitted by adsorption kinetics. As compared to BET, Temkin, Freundlich and Dubinin-Radushkevich model, Langmuir model is suitable for adsorption isotherm. Thermodynamic studies suggest adsorption process’s endothermic nature and spontaneity. The adsorption advances through π-π interaction, H-bonding and electrostatic attraction. Reusability study reveals the prepared adsorbent is a promising as well as cost effective sorbent for high efficiency and excellent renewability.
