Abstract

In this paper, ozonation method is used to remove carbendazim from aquatic environment. In this method, the produced ozone gas passes through an injector and then is converted into little bubbles and finally is injected into the synthetic wastewater. Spectrophotometer was used to measure carbendazim concentration. The complete factorial method was used to design the experiment. This design is considered to be repeated for two times for time parameters at five different levels of 5, 10, 15, 30 and 45 per minute, pH levels of 5, 6.73 and 9, and initial concentration of carbendazim levels of 2, 6, and 10 mg/l. The results showed that the maximum removal efficiency of carbendazim was 91% for a period of 15 minutes, pH level of 9 and concentration of 10 ppm and the most effective parameters on carbendazim removal efficiency have been initial carbendazim concentration, initial wastewater pH and ozonation time, respectively.
