1. Photodegradation of Fluoxetine Applying Different Photolytic Reactors: Evaluation of the Process Efficiency and Mechanism
Photolytic degradation of fluoxetine (FLX), a medicine commonly known as Prozac®, was evaluated by using different photochemical processes. The ultraviolet/microwave (UV/MW) process showed higher efficiency in all the aspects evaluated in this study. The energy consumption was equivalent to 1.94 × 10-4 kW h mg-1 L (UV/MW), while in the UV process the value

2. Degradação do fungicida tiofanato metílico pelo processo foto-Fenton em reatores anular e solar
Os efluentes das indústrias de agrotóxicos apresentam grande dificuldade quanto à sua descontaminação no meio ambiente e, além disso, são caracterizados por possuírem alta carga orgânica e toxicidade. O grupo de pesquisa do Centro de Engenharia de Sistemas Químicos (CESQ) do Departamento de Engenharia Química da Escola Politécnica da Universidade

3. Experimental study and mathematical modeling of hybrid solar reactor for phenol degradationby photo-Fenton process. / Estudo experimental e modelagem matemática de reator solar híbrido para degradação de fenol em solução aquosa pelo processo foto-Fenton.
Wastewaters containing hazardous, or recalcitrant organic substances are generated in a wide variety of industrial processes. The inadequate management of these effluents can cause contamination of underground and surface water. Their treatment by conventional processes may not be technically efficient, and usually prevents effluents from being discarded or

4. Use of solar energy in the treatment of water contaminated with phenol by photochemical processes
The solar driven photo-Fenton process for treating water containing phenol as a contaminant has been evaluated by means of pilot-scale experiments with a parabolic trough solar reactor (PTR). The effects of Fe(II) (0.04-1.0 mmol L-1), H2O2 (7-270 mmol L-1), initial phenol concentration (100 and 500 mg C L-1), solar radiation, and operation mode (batch and fe

6. Experimental development and mathematical simulation of the photochemically initiated methyl methacrylate pre-polymerization process. / Desenvolvimento experimental e simulação matemática do processo de pré-polimerização fotoiniciada do metacrilato de metila (MMA).
The aim of this work is the experimental optimization, the mathematical modeling and the simulation of the photochemically initiated pre-polymerization process of methyl methacrylate (MMA). According to the industrial interests a pre-polymer of narrow molecular weight distribution (MWD) and defined weight concentration was pointed as an optimum since it impr

7. Estudo e projeto de reatores fotoquimicos para tratamento de efluentes liquidos / Study and design of photochemical reactors to treat liquid effluents
Wasterwater treatment has become a fundamental stage of industrial processes. Most wastewater treatment are currently based on biological processes. However, some types of wastewater cannot be treated by such processes due to the fact of possessing toxic. Therefore, the Advanced Oxidation Process (AOP) can be used with success in such wastewater remediation.
