Santos, A. C. V. Application of Sequential Injection Analysis (SIA) and Statistical Methods for the Optimization of Advanced Oxidative Processes Aiming the Treatment of Coatings Industry Samples. 2010. 129p. PhD Thesis – Graduate Program In Chemistry. Instituto de Quimica, Universidade de Sao Paulo, Sao Paulo. This Thesis describes the use of Sequential Injection Analysis (SIA) and statistical methods aiming the optimization of the treatment processes of coatings samples by Advanced Oxidative Processes (AOP’s), specifically by Fenton and photo-Fenton reactions. Studies were performed with model compounds, alizarin red S for optimization of Fenton parameters and a copper phthalocyanine-3,4′,4′′,4′′′-tetrasulfonic acid tetrasodium salt dye for optimization of photo-Fenton parameters in a homemade photo reactor. At SIA established conditions, it was observed a degradation of 99.7% of alizarin and 97% of the phthalocyanine dye. A sample of wastewater from the coatings industry was also considered; for this matrix, results showed a sample mineralization of 79% after photo-Fenton and 45% after Fenton reactions.
