Neste estudo, os processos oxidativos avançados (POAs) Fenton e Foto-Fenton, foram estudados na degradação dos corantes alimentícios azul Brilhante FCF, vermelho Ponceau 4R e amarelo tartrazina. A presença de corantes alimentícios em efluentes geram problemas ambientais devido à alta coloração e estabilidade dessas moléculas orgânicas, as quais são de difícil degradação e podem gerar subprodutos com alta toxicidade. Os Processos de Fenton e Foto-Fenton apresentam eficiência na degradação de corantes, combinado as vantagens de simplicidade e baixo custo do processo. Foram estudados os POAs, Fenton [combinando o uso de Ferro/peróxido de hidrogênio (H2O2, 36 % v/v) ] e Foto-Fenton [Ferro/peróxido de hidrogênio (H2O2, 36 % v/v) /luz ultravioleta (UV) ]. Os parâmetros de tempo reacional, concentração e tempo de exposição a luz UV, foram avaliados para os corantes descritos com ambos POAs. Os resultados obtidos exibiram grande efetividade para os POAs Fenton e Foto-Fenton na degradação dos corantes azul Brilhante FCF, vermelho Ponceau 4R e amarelo tartrazina. O processo Fenton (Fe/H2O2) apresentou degradação mais efetiva em menor tempo reacional para os corantes estudados. Assim, podemos destacar que os POAs estudados Fenton e Foto-Fenton, destacam-se como uma importante metodologia para tratar efluentes industriais contendo corantes alimentícios, combinando as vantagens de facilidade, efetividade e baixo custo no processo.

Abstract Background In many countries, the levels of synthetic food additives causing harm to humans have been determined and their use has been controlled by legal regulations. Sensitive, accurate and low-cost analysis methods are required for food additive determination. Objective In this study, a fast high performance liquid chromatography-diode array detection (HPLC-DAD) analytical methodology for quantification of sodium benzoate, potassium sorbate, ponceau 4R, and carmoisine in a beverage was proposed. Methods Partial least squares (PLS) and principal component regression (PCR) multivariate calibration methods applied to chromatograms with overlapped peaks were used to establish a green and smart method with short isocratic elution. A series of synthetic solutions including different concentrations of analytes were used to test the prediction ability of the developed methods. Conclusions The average recoveries for all target analytes were in the range of 98.27–101.37% with average relative prediction errors of less than 3%. The proposed chemometrics-assisted HPLC-DAD methods were implemented to a beverage successfully. Analysis results from sodium benzoate, potassium sorbate, ponceau 4R, and carmoisine in a beverage by PLS-2 and PCR were statistically compared with conventional HPLC. Highlights The HPLC methods coupled with the PLS-2 and PCR algorithm could provide a simple, quick and accurate strategy for simultaneous determination of sodium benzoate, potassium sorbate, ponceau 4R, and carmoisine in a beverage sample.
