Enhanced Degradation of Sulfonamide Antibiotics by UV Irradiation Combined with Persulfate

نویسندگان

چکیده

In this study, the degradation of sulfonamide antibiotics was investigated through persulfate-enhanced UV advanced oxidation process. Factors that may affect efficiency were analyzed. Results showed persulfate imposed a significant enhancement on process during sulfathiazole degradation. The combined UV/persulfate can effectively remove about 96% within 60 min. With increase in dosage persulfate, removal increased as well. Different water matrix almost had no effect efficiency. Two intermediates found It be predicted has broad application prospect for removing treatment.

Microbial Degradation of Sulfonamide Antibiotics

Certain microbes can transform antibiotics in the environment. However, little is known about the identity of these microbes and their antibiotic biotransformation processes. The objectives of this study were to (1) isolate bacterial strains capable of transforming antibiotics, (2) determine the biotransformation kinetics of antibiotics, (3) characterize the effects of background carbons on the...

Degradation of acrylonitrile-butadiene-styrene and polycarbonate by UV irradiation

The e€ects of ultra-violet irradiation on the microstructure of an oxygen free polymer viz., acrylonitrile-butadiene-styrene and a polymer containing oxygen viz., polycarbonate have been investigated using positron annihilation lifetime measurement. Lifetime results in both polymers in the early stages of irradiation indicate that chain-scission leading to free radical formation is the predomin...

Oxidative Degradation of 2-chlorophenol by Persulfate

The degradation of 2-chlorophenol (2-CP) by persulfate was investigated. The kinetics of persulfate oxidation of 2-chlorophenol in aqueous solutions at various pH, oxidant concentration, temperature, Fe2+ and Cu2+ ions content was studied. Maximum of 2-CP degradation occurred at pH 8. The oxidation rate of 2-CP increased with increasing the persulfate molar excess. The degradation process was s...
