Item Aplicación de la técnica Espectroscopía Raman para la determinación de microplásticos en el agua potable(Universidad Santiago de Cali, 2025) Collazos Reina, Jhon Jairo; Morales Morales, Jimmy Alexander (Director)The presence of microplastics in the environment represents a chemical, environmental, and social issue that has been increasing over the past few decades. This monograph addresses this situation, focusing particularly on the detection of microplastics in tap and drinking water across various cities and countries, thus evidencing their presence in urban water systems worldwide. Special attention is given to the Raman spectroscopy technique and its variants (μRaman). This analytical method is selective and non-destructive, allowing for the efficient identification and quantification of various types of microplastics at microscopic and even nanometric scales. Due to its high sensitivity and specificity, this technique has become a key tool in the analysis of emerging pollutants, surpassing some limitations of other methodologies such as Fourier-transform infrared spectroscopy (FTIR) and scanning electron microscopy with energy-dispersive X-ray spectroscopy (SEM/EDX). Several recent studies have reported varying concentrations of microplastics in drinking water samples using Raman spectroscopy as the method of identification. These results not only validate the effectiveness of the technique but also highlight the need to implement monitoring and control systems to prevent microplastics from entering water distribution networks. Although the presence of microplastics in drinking water has been widely documented, their specific effects on human health remain inconclusive. However, their persistence, bioaccumulation potential, and toxicity make their study a continued priority for the scientific community from a preventive perspective.
