چکیده

This paper studies the effect of photosensitizer (acetone, H(2)O(2), surfactant and pigment) on photodegradation of diclofenac (DCF) under simulated sunlight. The results demonstrate that degradation pathways proceed via pseudo first-order kinetics in all cases. The photodegradation rate was found to increase with increasing acetone and H(2)O(2). Surfactant and pigment inhibited the photodegradation of DCF. Finally, four kinds of main degradation products were observed by high performance liquid chromatography/mass spectrometry and their chemical structures were suggested.

[Photodegradation of nonylphenol polyethoxylates in aqueous solution].

Two lamps, including simulated sunlight lamp and UVA-365 nm lamp, were used to study the kinetics and changes of component distribution of NPEOs mixture in solution during photodegradation, as well as the effect of H2O2 on the photodegradation. LC-MS was used to analyze the products of NPEOs photodegradation. It was found that photodegradation of NPEOs occurred under both simulated sunlight and...

Photostability and toxicity of finasteride, diclofenac and naproxen under simulating sunlight exposure: evaluation of the toxicity trend and of the packaging photoprotection

BACKGROUND Drugs photostability plays two different opposite roles; a real advantage arises considering the longer expiration time of the drugs while the consequent persistence in the environment involves an obvious negative effect bound to their harmfulness.On this basis we tested the photostability and toxicity of three pharmaceutical active principles: Finasteride, Diclofenac and Naproxen. T...

Occurrence and Fate of the Pharmaceutical Drug Diclofenac in Surface Waters: Rapid Photodegradation in a Lake

The pharmaceutical drug diclofenac (2-[(2,6-dichlorophenyl)amino]benzeneacetic acid) was detected in rivers and lakes in Switzerland. The data strongly suggest inputs of diclofenac from human medical use via wastewater treatment plants. Interestingly, the concentrations in a major tributary to a lake (Greifensee) were significantly higher (up to 370 ng/L) than those in the outflow of this lake ...

Photodegradation of Insecticide Chlorpyrifos in Aqueous Solution under Simulated Solar Light Irradiation Conditions using Babolrood River Water

Chlorpyrifos is an organophosphate insecticide, used to control foliage and soil-borne insect pests on a variety of food and feed crops. In the natural environment, Chlorpyrifos can be degraded  through  several  possible  processes,  including  photodegradation, biodegradation,  and hydrolysis.  In  the  present  work  the  photodegradation  and  environmental  fate  of  Chlorpyrifos  in aqueo...
