An Effective Microwave-Assisted Synthesis of MOF235 with Excellent Adsorption of Acid Chrome Blue K

الملخص EN

An efficient, rapid, and fast kinetics of the metal-organic framework MOF235 was successfully prepared by microwave-assisted thermolysis strategy.

Fourier transform infrared spectra (FTIR), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), N2 adsorption-desorption isotherm, and scanning electron microscopy (SEM) were used to characterize the samples.

Experimental results revealed the suitability of MOF235 for use as an adsorbent for acid chrome blue K.

The maximum adsorption capacity of acid chrome blue K onto MOF235 can reach to 591.79 mg g-1 at 293 K.

The sorption behavior fitted to the pseudo-second-order kinetic model and the Langmuir isotherm.

Adsorption of acid chrome blue K is a spontaneous and endothermic process.

Therefore, the as-prepared MOF235 displays a great potential for environmental purification.
