Abstract

The use of nanomaterials in wastewater treatment has gained importance. Nano-structured adsorbents have good adsorption potential due to their properties such as large surface area. In this study, removal of AO74 (Acid Orange 74) from the waters with TiO 2 nanoparticles were investigated. TiO 2 nanoparticles were synthesized by sol–gel method. The X-ray diffraction (XRD), Scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy ( FTIR ) and Ultraviolet – visible spectroscopy (UV–VIS) spectrometer techniques were used to characterize the synthesized products. Stability analysis was performed by zeta potential analysis. The anatase phase of the TiO 2 nanoparticles was confirmed by XRD analysis. The SEM micrographs revealed the spherical-like morphology with average diameter of about 32 nm which agrees with XRD results. FTIR spectra show the vibrational mode of TiO 2 around 600 cm -1 . Absorption peak in the UV region at 320 nm are observed. This peak is characteristics of nano-sized TiO 2 nanoparticles. If the measured zeta potential absolute value is greater than 35 mV, it can be said that the produced nanofluid is stable. The zeta potential value greater than 35 mV in all measurements in this study, so that the synthesized TiO 2 nanoparticle is stable in the fluid medium. pH (2-5), contact time (10-120 min) and initial dye concentration (20-100 mg / L) were investigated to determine the adsorption potential of TiO 2 nanoparticles . The optimum parameters for adsorption of AO74 were determined as pH and contact time, respectively: 5 and 75 minutes. The adsorption system is compatible with Langmuir and Freundlich isotherms . As a result, TiO 2 nanoparticles were identified as suitable adsorbent for removal of AO74.
