Síntesis De Sensores Para Detección De Iones Metálicos En Solución Basados En Análogos De Curcumina-Aminoácidos

Abstract

Water pollution is a serious issue for human health and the environment, making it crucial to monitor water quality. Traditional methods such as atomic absorption spectroscopy and plasma spectrometry are effective but costly and slow. In response, fluorogenic and chromogenic methods have been developed, offering a rapid and efficient alternative for detecting traces of metal ions in solution. These sensors, particularly those with fluorescence properties, are valued for their specificity and sensitivity, making them ideal for use in remote areas. This study advances the development of fluorescent optical sensors and describes the synthesis of new heptanoid β-diketone compounds, like curcumin but more effective in detecting metal ions. These compounds exhibit fluorescent properties when reacting with transition metals, offering new possibilities for pollutant detection. The characterization of these sensors is carried out using advanced techniques such as infrared spectroscopy and nuclear magnetic resonance, and their efficacy and toxicity are assessed through ultraviolet-visible spectrophotometry and ecotoxicological tests on onion bulbs.
