Oxidation of Aqueous Dexamethasone Solution by Gas-Phase Pulsed Corona Discharge
نویسندگان
چکیده
The most widely used anti-inflammatory corticosteroid dexamethasone (DXM), frequently detected in waterbodies due to its massive consumption and incomplete removal wastewater treatment processes, was experimentally studied for oxidation with gas-phase pulsed corona discharge (PCD) varied pulse repetition frequency, pH, DXM initial concentration additions of surfactant sodium dodecyl sulphate (SDS) tert-butyl alcohol (TBA). experimental study also included ozonation as compared PCD energy efficiency. advantageous efficiency observed wide spans pH concentrations surpassing by about 2.4 times. Identified transformation by- end-products (fluoride acetate), well the impact radical scavengers, point prevalent DXM. Somewhat increased toxicity on course PCD-treatment high presents a subject further studies.

Degradation of Aqueous Phase Trichloroethylene Using Pulsed Corona Discharge
Pulsed corona discharge has been found to be an effective method for the removal of trichloroethylene (TCE) from the aqueous phase. Almost complete degradation over one hour was observed irrespective of the electrolyte used in the solution. The degradation rates observed in these experiments are higher than those for other organic compounds such as phenol in pulsed corona reactors, thereby sugg...
متن کاملRemoval of Nonylphenol by Pulsed Corona Discharge in Water
Degradation of technical mixture of nonylphenol by the pulsed corona discharge in water has been investigated. It was shown that non-thermal plasma generated by the discharge can effectively remove nonylphenol from water. Degradation of nonylphenol followed first order kinetics. The removal efficiency was dependent on the solution conductivity, while a higher degree of degradation was obtained ...

متن کاملLaboratory studies of the aqueous-phase oxidation of polyols: submicron particles vs. bulk aqueous solution
Oxidation in the atmospheric aqueous phase (cloud droplets and deliquesced particles) has received recent attention as a potential pathway for the formation of highly oxidized organic aerosol. Most laboratory studies of aqueous-phase oxidation, however, are carried out in bulk solutions rather than aqueous droplets. Here we describe experiments in which aqueous oxidation of polyols (water-solub...
