چکیده	The adsorptive removal of anionic dyes were investigated over two isoreticular nanoporous Zn(II)-MOFs known as TMU-16 and TMU-16-NH 2 in view of the influence of an amine group on the adsorption capac- ity. Adsorption isotherms, thermodynamics and kinetics parameters of the sorbents were studied and also effective factors on dye adsorption have been optimized. Thermodynamic and kinetic results revealed ad- sorption over two MOFs is spontaneous and pseudo-second order, as well as TMU-16-NH 2 showed higher removal yield to TMU-16 because of forming hydrogen bonding between dyes and amine groups. These MOFs showed great adsorption uptakes for anionic dyes than other porous materials that reported pre- viously. Adsorption mechanism could be explained by electrostatic and hydrogen bonding interactions. Importantly TMU-16 and TMU-16-NH 2 due to high adsorption capacity and stability of structures could be employed as excellent sorbents to remove harmful dyes in contaminated water
