Reactor photochemical characterization for application in advanced oxidative process
Abstract
O presente estudo visa ampliar a compreensão dos processos fotoquímicos por meio do cálculo de eficiência quântica da lâmpada Hg-MDEL, além de discutir sobre a aplicação ambiental desse modelo de lâmpada em processos oxidativos avançados. Esse conjunto de informações são de imensa relevância para ampliar a aplicação das Hg-MDEL em estudos ambientais diversos. Deste modo, um reator fotoquímico composto por uma lâmpada de mercúrio sem eletrodos de descarga (Hg-MDEL) acionada por micro-ondas (MW) foi avaliado a partir de estudos actinométricos KI/KIO3. Os espectros de emissão foram caracterizados junto as regiões UV-A, UV-B, UV-C e visível por meio de um espectrorradiômetro, apresentando correlação linear com a variação de potência micro-ondas aplicada. A conversão fotoquímica de KI/KIO3 em I3- foi de até 0,073 mmol L-1 quando a concentração inicial de KI era de 0,1 mol L-1 e 0,65 mmol L-1 quando a concentração de KI era de 0,7 mol L-1, aplicando uma potência micro-ondas de 600 e 400 W, respectivamente. Estes resultados indicam que para potências mais elevadas, a emissão de fótons junto ao reator é mais significativa, contribuindo de modo ativo para a formação de I3-.
