In this thesis, the application of metal-organic nanostructures (MOFs) in the removal of some dye organic compounds by solid phase extraction method was studied. Ultrasonic wavelengths were used to absorb absorbents and colors, which resulted a minimal time to remove. Three variable parameters including adsorbent amount, ultrasound wavelength and pH were investigated to remove Congo red and methylene green colors. The optimization of effective variable parameters for the simultaneous removal of colors was performed by using central composite method of design software, and response surface technique, and the optimal conditions for removal of colors with this adsorbent, for the Congo red, 15 mg of absorbance, pH =4 and 10 min and also for Methylene green 10 mg of absorbance, pH =10 and 5 min were obtained. The kinetic and equilibrium studies of absorption processes were also studied for each of colors. The kinetic model of intended adsorbent adsorption for both of colors was pseudo-second-order and equilibrium models of Langmuir-temperature equilibrium types. The adsorption capacity of adsorbent for Congo red and methylene green was 242.43 mg /g and 283.58 mg /g respectively.
