Degradation of ciprofloxacin Antibiotic by ultrasonic/persulfate in persence of synthesized zero valent zinc nanoparticles

Backgrond: Pharmaceutical products, particularly antibiotics such pollutants are evolving due to the cumulative effects, adverse effects and drug resistance is a major concern in the control environment. The purpose of this work is to investigate the feasibility and potential of iron nanoparticles in the aqueous solution being removed antibiotics.
In this study, the performance activated persulfate with zero-valent Zinc nanoparticles in the presence of ultrasound in the analysis of antibiotics was investigated. The effect of process parameters such as pH of the solution (2.97-10.53), concentration Potassium persulfate (194.33-1200mg/l) and the zero-valent zinc (12.73-147.27mg/l) in reaction time 0-180 min using a batch chamber ultrasonic were studied. A statistical procedure was used to optimize the parameters of the RSM model. Antibiotics are measured based on COD vials and DR-5000 spectrophotometer was used.
The results showed that the initial pH of the solution is the most important influential parameters. The addition of potassium persulfate and zero valent zinc in the samples was enhanced performance. Optimum efficiency achieved in 50 mg/l concentration antibiotics, potassium persulfate 1200 mg/l, the zero- zinc 120 mg /l, pH 4.5.
The results of this study demonstrate acceptable performance persulfate activated process with zero-valent iron and zinc nanoparticles on ultrasound in the presence of antibiotic.
