| description | In this study, a strategy using Partial Least Squares (PLS) as a chemometric tool to establish the robustness of the photosensitized degradation process of Bisphenol A in simulated effluents was assessed. In the first stage of the research, the validation of the methodology that allows the quantification of Bisphenol A (BPA) mixed with the photosensitizer Eosin Y (EOS) in aqueous solution was carried out. Through the use of spectrophotometry as monitoring technique, it was possible to establish the optimal number of factors and the wavelength range, and to determine that was possible to ensure the quantification of BPA by means of PLS, by demonstrating complex formation between BPA and EOS. The RMSE results were 0.004237 at 284 nm and 0.009167 at 524 nm, demonstrating good robustness in the analysis. Next, preliminary tests were carried out on the effect of direct light using a mercury lamp as a source of irradiation. In the case of BPA, it was determined that 100% degradation is achieved at 100 minutes.

In the case of BPA, it was determined that 100% degradation is achieved at 100 minutes. En este estudio se propuso evaluar una estrategia utilizando Partial Least Squares (PLS) como herramienta quimiométrica para establecer la robustez del proceso de degradación fotosensibilizada de Bisfenol A (BPA) en efluentes simulados. En esta la etapa del trabajo de investigación, se llevó a cabo la validación de la metodología que permitió la cuantificación de BPA mezclado con el fotosensibilizador Eosin Y (EOS) en solución acuosa. Utilizando la espectrofotometría como técnica de seguimiento, fue posible establecer el número óptimo de factores y el rango de longitud de onda, y determinar que es posible asegurar la cuantificación de BPA mediante PLS al demostrar la formación de complejos entre BPA y EOS. Los resultados de RMSE fueron 0,004237 a 284 nm y 0,009167 a 524 nm, lo que demuestra una buena solidez en el análisis. A continuación, se realizaron pruebas preliminares sobre el efecto de la luz directa utilizando una lámpara de mercurio como fuente de irradiación. En el caso del BPA se determinó que se alcanza el 100% de degradación a los 100 minutos. El fotosensibilizador se fotodegradó a los 50 minutos de exposición a la luz directa. La mezcla de los dos compuestos en el análisis preliminar podría demostrar un efecto de pantalla por parte del fotosensibilizador.
