چکیده

Textile industry is one of the largest industries producing dyeing wastewater and endangering aquatics life. This study investigated the efficiency of calcium peroxide nanoparticles in removal of Reactive Red 198 from synthetic and real wastewater. Characteristics of synthesized nanoparticles was determined by TEM and XRD. The effect of solution pH (3-13), initial concentration of dye (10-300 mg/L), contact time (5-90 min) and adsorbent dosage (0.05-0.6 g) was investigated. Synthesized adsorbent was of uniform spherical shape and approximately 15-25 nm in diameter. The optimum pH for removal of RR198 was 3-7. The equilibrium contact time was 50 minutes and optimum dosage of adsorbent was 0.4 g/100 mL in these optimum conditions, removal efficiency in synthetic and real sample was 99.58 and 76.18 percent respectively. Based on the results calcium peroxide is an efficient adsorbent in removing RR198 and can be used as an applied method in treating textile wastewaters.
