Efficiency of the Electrocoagulation Process with Iron and Aluminum Electrodes Regarding the Removal of Cefazolin Antibiotics from the Hospital Wastewater
The entry of antibiotic residues into water resources along with domestic sewage, pharmaceutical, hospital, veterinary, agricultural products and fish ponds is important due to their sustainability and non-degradability. More than 80 types of pharmaceutical compounds and their metabolites have been found in water resources. Annually, about (100 to 200) thousand tons of antibiotics, which are about 15% of all drugs, are consumed in the world. Concentration of antibiotics in wastewater in the range of 3 /. Up to 200 micrograms per liter and above. Advanced oxidation (AOPs), catalytic, photoelectrocatalyst, ozone, hydrogen peroxide, photon reactions, and photofenton and membrane reactions have been used.
A total of 108 effluent samples were taken at pH 4, 7, and 9 at 10, 30, and 50 minutes at 15, 30, and 50 volts after the electrocoagulation process. Determination of cefazolin by HPLC Knauer device with C18 column equipped with UV with movable strontium phase and HPLC Grade water of Merck company with 30 to 70 ratio, set at pH equal to 8 with triethylamine, flow 0.5. Ml per minute and wavelength 270 nm, TS with 2540 B, pH with Eutech5500 device, COD with, 5220 D Alk with 2320A methods.
The removal efficiency of Alk, TS, COD and CFZ is 69.49%, 67%, 86% and 79.42%, respectively.
Electrocoagulation was used to reduce the pollution load of wastewater containing antibiotic compounds and resistant and emerging organic pollutants before discharging wastewater into the environment in order to purify the pollutant into an environmentally friendly process.
