PROTOTIPAGEM DE MICRORREATORES FOTOCATALÍTICOS E TESTES DE FOTODEGRADAÇÃO DE CORANTES ORGÂNICOS

A photocatalytic microreactor is defined as a microfluidic device, which is integrated with a photocatalytic coating of TiO₂ deposited on the inner surface of microchannels. This device is capable of degradation of organic dye solution in water in a continuous flow under the action of ultraviolet light. The objectives of this work were to present a rapid and economically viable approach for the prototyping photocatalytic microfluidic devices and to evaluate their photodegradation capability for organic dyes by ultraviolet-visible spectrophotometry. Prototyping of polydimethylsilo...
