Abstract
The purpose of this study was to investigate the efficiency removal of the antibiotic Tinidazol by hybrid system of ultrasonic/nZVI/H2O2 (US/nZVI/H2O2) in aquatic environment. It examined the effect of variables such as concentration of antibiotic, nZVI and H2O2, frequency of US and pH. Also the performance of system in removal of COD and electrical energy consumed by the ultrasonic bath was investigated. Findings showed the best efficiency (93%) for system in pH 3, concentration hydrogen peroxide of 1M, amount of 0.2 g of zero valent iron nanoparticles and 130 kHz radiation frequency. According to the results US/nZVI/H2O2 method can be good performance in removal of antibiotics Tinidazol and similar pollutants.
