Degradation of diclofenac in aqueous solution by homogeneous and heterogeneous photolysis
Background: Pharmaceuticals have arisen as emerging environmental pollutants due to their potential impact on humans, animals and microorganisms even at low concentrations. Conventional wastewater treatment plants are known to be ineffective for removal of many pharmaceuticals present in wastewater. Advanced oxidation processes are one of the most promising treatment technologies for degradatio...
متن کاملDegradation Kinetics of Diclofenac in Water by Fenton’s Oxidation
An extensively used non-steroidal anti-inflammatory drug (NAID) diclofenac (DCF) is reported to be present in the environment. Several adverse effects have been reported due to presence of DCF and hence it should be removed from the environment. Among several treatment methods, classic Fenton oxidation is found to be an effective process for the removal of organic contaminants. In the present s...
متن کاملHomogeneous and Heterogeneous Photocatalytic Water Oxidation by Persulfate.
Photocatalytic water oxidation by persulfate (Na2 S2 O8 ) with [Ru(bpy)3 ](2+) (bpy=2,2'-bipyridine) as a photocatalyst provides a standard protocol to study the catalytic reactivity of water oxidation catalysts. The yield of evolved oxygen per persulfate is regarded as a good index for the catalytic reactivity because the oxidation of bpy of [Ru(bpy)3 ](2+) and organic ligands of catalysts com...
متن کاملAromatic Compound Degradation in Water Using a Combination of Sonolysis and Ozonolysis
The combination of sonolysis and ozonolysis as an advanced oxidation process was investigated to gain insight into factors affecting enhancement of the combined system. Sonolysis, ozonolysis, and a combination of the two were used to facilitate the degradation of three known organic contaminants, nitrobenzene (NB), 4-nitrophenol (4NP), and 4-chlorophenol (4-CP), in water. Experiments were perfo...
متن کاملDegradation of Diclofenac Sodium under Solar Light Irradiation by Photocatalytic Performance of ZnO and V2O5
Pharmaceutical pollutants are one of the most important issues of modern life and their negative effects on the environment and human health are undeniable. In the present work, the effectiveness of the photocatalytic process was studied by two semiconductors (ZnO and V2O5) in order to remove the Diclofenac Sodium completely under solar irradiation. The study examined the impact of parameters s...
