Background: In this study, adsorbentn process performance was assessed using nickel oxide nanoparticles for wastewater treatment containing mono azo Orange II dye in a laboratory scale. Methods: The effects of various factors such as adsorbent dosage, contact time, pH and initial dye concentration were investigated. Findings: Based on the obtained results, the optimum pH range to dye removal is acidic pH and under these conditions, complete removal of the 50 mg/L dye can be achieved by using 0.6 g/L of nickel oxide. This concentration of nickel oxide was determined as the optimum concentration. Although increasing dye concentration caused a decrease in the efficiency process, but a considerable efficiency was obtained in 100 mg/L dye concentration. Conclusion: The data showed that the nickel oxide nanoparticles could be used as an efficient adsorbent for the decolorization of azo dyes.
