Title : Study of ketoprofen removel kinetics by a semiconductor material in a double tube reactor
Abstract:
Sustainable development and respect for the environment are topical issues. Pharmaceutical releases pose significant processing problems, especially since the releases are not fully biodegraded by biological processes. Studies on effluents from sewage treatment plants (STEPs) show that several pharmaceuticals are not completely eliminated and are released as contaminants into receiving waters. These molecules are found in wastewater and can have effects on biomass (Naitali and Ghoualem, 2014) and (Ghoualem and Naitali, 2012).
In Algeria, according to the statement of director general of the central pharmacy hospitals (PCH) at the Liberté newspaper forum published on April 16, 2015, there are currently over 5,000 drugs, 25 therapeutic clauses and 132 production units nationwide. Advanced oxidation processes are a way of eliminating organic micropollutants including pharmaceutical pollutants in aqueous solution. In photo-catalytic processes, the use of a semiconductor due to its oxidizing properties leads to the production of hydroxyl radicals which serve to oxidize the organic material. The use of biological processes for the treatment of pharmaceutical pollution has shown the efficiency of this process, 2013), (Naitali and Ghoualem, 2015). Recent studies on water treatment, advanced AOP oxidation processes (Advanced Oxidation Process) provide a solution by proving their effectiveness, allowing the mineralization in an aqueous medium of the organic molecules toxic to the man and the environment (Naitali and Ghoualem, 2014). The objective of our research is the study of photo degradation in the aquatic environment of ketoprofen. The results showed that conversions of Ketoprofen decrease with increasing ZnO concentration. The increase in degradation rate of ketoprofen during the increase of ZnO concentration can be explained by the excess of hydroxyl radicals generated in the solution.
Audience Takeaway Notes:
- The objective of our research is the study of photo degradation in the aquatic environment of ketoprofen in new reactor. The kinetic degradation of the organic matter has been done.
- The aim of this work is to study the feasibility photo catalytic process that applies to the processing of non- soluble macrolide antibiotic in the water while playing on the surface properties of solvent and drug
