  4. Abstract:
  5. In this paper, copper oxide nanoparticle was synthesized, and its surface was modified using N-(2-aminoethyl)-3-(trimethoxysilyl)propylamine. The bi-amino surface functionalized nanoparticle (BASFN) was used to remove anionic dyes from single and binary systems. The scanning electron microscopy (SEM), Fourier transform infrared (FTIR) spectroscopy, energy-dispersive X-ray spectroscopy (EDAX) and X-ray diffraction 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 on BASFN followed pseudo-second order. The results showed that the experimental data were correlated reasonably well by Langmuir and Freundlich isotherm in single and binary system, respectively. The maximum dye adsorption capacity (Q0) of BASFN was 217 and 250 mg/g for DR80 and DG6, respectively. © 2017 Desalination Publications. All rights reserved
