Degradation 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...

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...

Enhancing Photocatalytic Activity of Nitrogen Doped TiO2 for Degradation of 4-Chlorophenol under Solar Light Irradiation

The nitrogen doped TiO2 as heterogeneous photocatalyst via sol-gel method were successfully synthesized. The physicochemical, morphological and textural characteristics of the obtained TiO2 samples were characterized by advanced analysis techniques. The photocatalytic activity of the samples were evaluated for degradation of 4-CP under solar irradiation. The as-synthesized photocatalysts were c...

Forecasting Direct Normal Irradiation at Djibouti Using Artificial Neural Network

In this paper Artificial Neural Network (ANN) is used to predict the solar irradiation in Djibouti for the first Time that is useful to the integration of Concentrating Solar Power (CSP) and sites selections for new or future solar plants as part of solar energy development. An ANN algorithm was developed to establish a forward/reverse correspondence between the latitude, longitude, altitude an...
