  7. Abstract:
  8. During the recent years, shortage of drinking water is one of the concerns of the society and necessity of purification of contaminated water are taken into consideration. Different methods to be developed to prevent problematic pollutions. Among these different methods the most common one is adsorption. In this thesis, the copper oxide nanoparticle was synthesized and its surface was modified using N-(2-aminoethyl)-3-(trimethoxysilyl)propylamine. The bi-amino surface functionalized nanoparticle was used to remove anionic dyes from single and binary systems. The scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), Energy-dispersive X-ray spectroscopy (EDAX) and X-ray diffraction (XRD) were used to characterize the nanoparticle. Direct Red 80 (DR80) and Direct Green 6 (DG6) were used as anionic dyes. The effect of adsorbent dosage, dye concentration and pH on dye removal was evaluated. Kinetic of dye adsorption followed pseudo-second order for single and binary systems. The results showed that the experimental data were correlated reasonably well by Langmuir isotherm in single system, and in binary system dye adsorption followed Freundlich isotherm. Furthermore, according to desorption studies, dye release was occurred to a large extent at pH=11. The results indicate that the functionalized copper oxide nanoparticle can be used as a suitable adsorbent for dye removal from anionic colored wastewater
