In this research, UiO-66 and its magnetic nanocomposite with Fe3O4, named Fe3O4@UiO-66, were synthesized via a simple solvothermal method and utilized as solid adsorbent for the removal of anionic methyl red (MR) dye and cationic methylene blue (MB) dye from contaminated water. The kinetic study indicated that the pseudo-second order kinetic model is suitbale for illustration of adsorption of MR and MB onto pristine UiO-66 and Fe3O4@UiO-66 nanoparticles. The experimental adsorption results displayed that the synthesized Fe3O4@UiO-66 nanoparticles presented higher adsorption capacity for anionic dyes compared to cationic dyes in both single and binary dye solutions. It was deduced that the electrostatic interactions and hydrogen bonding between anionic dye molecules and adsorbents were the main mechanisms for selective adsorption of these dyes onto synthesized adsorbents. The appropriate removal efficiency, rapid adsorption kinetic, high water stability, and good separation make Fe3O4@UiO-66 nanoparticles attractive candidate for selective separation of anionic MR from cationic MB in the mixture of both dyes
