Resumo: dc.description.abstractThis article aims to verify the efficiency and influence of pH, concentration and aeration on the heterogeneous photocatalysis of methylene blue. Dyes are used massively by the global textile industry and harm water quality when discarded into bodies of water. In particular, in addition to exhibiting toxicological aspects, the methylene blue dye makes it difficult for aquatic plants to carry out photosynthesis. By employing heterogeneous photocatalysis, associating TiO2 with UV light, we sought to verify whether methylene blue can be removed from water. Factorial planning 23 and the normal probability graph showed that pH and TiO2 concentration, as well as their interaction, directly influence the process, while aeration is less significant, given the excessive formation of bubbles and low dissolved oxygen levels. Despite possible improvements to be suggested to the experiment, the photocatalytic treatment proved to be successful with 89.01% global efficiency.-
