description Industrialized cities like Tijuana dispose of a large amount of water with metallic elements content, as a result of by-products, which represent a health risk. A proposed alternative is the use of chemical sensors based on different mechanisms. The focus of this project is the study of bis-o-aminobenzamide macromolecules, as metal ion selector sensors with application in wastewater treatment. A series of five bis-o-aminobenzamide compounds were studied as chemical sensors capable of selecting and coordinating with metals dissolved in water, in addition to being able to remove these metals in the presence of the natural coagulant Pectin, which was extracted from the penca of the nopal. For this, different concentrations of the five compounds were prepared, the most suitable for the analyzes was selected and it was contacted with solutions of different ions. The compounds and their coordination were evaluated by fluorescence, UV-Visible and Zeta potential spectroscopies. In addition, SEM micrographs were obtained upon removal obtained. The five sensors evaluated have different fluorescence intensities. When in contact with some metal ions, a coordination was formed that reduces the emission of fluorescence. Fluorescent properties in solution were studied by varying the concentration of ligand and the study of its interaction with different metals of environmental interest was carried out. The influence of the nature of the central chain of interconnection on the fluorescent properties of the studied library was determined. These ligands have interesting fluorescent characteristics, which gives them a potential value as sensors for metals, presenting a sensitivity for the Cu +2 ion in all cases.

Las ciudades industrializadas como Tijuana desechan gran cantidad de agua con contenido de elementos metálico, resultado de los subproductos, que representan un riesgo para la salud. Una alternativa propuesta es el uso de sensores químicos basados en diferentes mecanismos. El enfoque de este proyecto es el estudio de macromoléculas bis-o-aminobenzamida, como sensores selectores de iones metálicos con aplicación en el tratamiento de aguas residuales. Se estudió una serie de cinco compuestos bis-o-aminobenzamidas como sensores químicos capaces de seleccionar y coordinar con metales disueltos en el agua, además de poder remover estos metales en presencia del coagulante natural Pectina la cual fue extraída de la penca del nopal. Para ello se preparó distintas concentraciones de los cinco compuestos, se seleccionó la más adecuada para los análisis y se puso en contacto con soluciones de distintos iones. Los compuestos y su coordinación fueron evaluados por espectroscopias de fluorescencia, UV-Visible y potencial Zeta. Además, se obtuvo micrografías SEM a la remoción obtenida. Los cinco sensores evaluados presentan distintas intensidades de fluorescencia, al estar en contacto con algunos iones metálicos se formaba una coordinación que abate la emisión de fluorescencia. Se estudiaron las propiedades fluorescentes en solución variando la concentración de ligando y se realizó el estudio de su interacción con diferentes metales de interés ambiental. Se determinó la influencia de la naturaleza de la cadena central de interconexión en las propiedades fluorescentes de la biblioteca estudiada. Estos ligandos presentan características fluorescentes interesantes, lo que les confiere un valor potencial como sensores para metales, presentando una sensibilidad para el ion Cu+2 en todos los casos.
