DEGRADATION OF SULFAMETHAZINE BY SE-FENTON METHOD
Abstract
Photodegradation is one of the important methods of antibiotic treatment in water environment. This paper studies the treatment effect of sulfamethazine by solar electric-Fenton (SE-Fenton) technology, observes the contribution of OH concentration to degradation, and involves the effect of pH value, voltage and Fe concentration on the treatment effect. The experiment shows that the degradation rate of sulfamethazine can be effectively improved by the solar-powered Fenton system. The optimum conditions for the degradation system are pH 3.0, 25 mg/L Fe concentration, and the applied voltage of 3 V. This study provides a basis for the removal of sulfonamide antibiotic contamination in water environment.
