| Summary: | This study investigates the removal of C.I. Acid Red 97 (AR97) as a model pollutant from textile industries using NiO nanoparticles in aqueous environments. The size and purity of NiO nanoparticles were initially determined using TEM and XRD techniques, respectively. The adsorption and removal efficiency of NiO nanoparticles for AR97 was then evaluated. The results indicated that NiO nanoparticles serve as effective adsorbent for AR97 removal. The effects of key operational parameters, including temperature, pH, amount of adsorbent, and initial pollutant concentration, on the adsorption efficiency of NiO nanoparticles were examined. The optimal conditions for AR97 removal were found to be a temperature of 25°C, pH of 2, adsorbent dosage of 4 g L-¹, and an initial AR97 concentration of 10 mg L-¹. |
