In the present study, a new step-based photoreactor was presented to investigate the degradation of Acid Red 73 under visible light irradiation. Four N-TiO2-coated alumina foams prepared by the modified sol-gel process were arranged in each step as photocatalyst. The experimental design methodology was employed to assess the interaction between the operational parameters in the step-...

The photooxidation of diethyl ether (C2H5OC2H5) and diisopropyl ether, (CH3)2CHOCH(CH3)2, in the presence of NOx was studied at the European Photoreactor (EUPHORE) in May 1998. The main objective of the experiments was to validate the degradation mechanisms that are based on data obtained from laboratory photoreactor studies. For diisopropyl ether, the experiments provided product yield data th...

2 ABSTRACT A novel photoreactor to facilitate electrosteric stabilization of colloidal polymer particles is presented. Anionic and cationic polystyrene particles having a diameter of ca. 100 nm and bearing a thin layer of photoinitiator are used as seed colloids. Anionic and cationic chains of weak or strong polyelectrolytes are grafted onto the surface of these particles. The polyelectrolyte c...

I n recent years, the reaction vessel by which chemists perform organic reactions has undergone major changes. No longer limited to round-bottom flasks, we can perform experiments in microwave ovens, flow reactors, and 96-well plates. Each of these technologies has enabled breakthroughs in organic synthesis not easily achieved using conventional flasks. In the rapid development of photoredox te...

Water pollution from emerging contaminants (ECs) or emerging pollutants is an important environmental problem. Heterogeneous photocatalytic treatment, as advanced oxidation treatment of wastewater effluents, has been proposed to solve this problem. In this paper, a heterogeneous photocatalytic process was studied for emergent contaminants removal using paracetamol as a model contaminant molecul...

In advanced oxidation processes (AOPs) operating in continuous mode, the flow rate and concentration of oxidants such as H2O2 at mixing point influent must be controlled so that oxidant residuals effluent are minimized while organic degradation is maximized. Designing a controller to regulate therefore, its photoreactor influent, needs determination reliable process dynamic model. this study, s...
