dc.description.abstractSe sintetizó un nuevo polímero orgánico con características que le permiten actuar como agente extractante de iones metálicos. Se fabricaron membranas a partir de policloruro de vinilo (PVC), plastificante éter de 2 nitrofenil octilo (NPOE) y polímero sintetizado que se emplearon en la extracción de oro a partir de disoluciones acuosas del metal. Se estudió, además, el efecto de la adición de tetrafenilborato de sodio (Na-TFB) para mejorar el intercambio iónico entre la solución de trabajo y la membrana fabricada. Se determinó la composición y el espesor de la membrana con la cual se obtuvo el mayor porcentaje de extracción de oro, así como la selectividad del material hacia Au3+ en presencia de otros iones metálicos (Cu2+, Pb2+, Ca2+, Zn2+, Fe3+, Ni2+ y Al3+), cada uno con una concentración inicial de 1,4x10-4 M. Los resultados mostraron que en un ciclo se alcanzaron porcentajes de extracción cercanos al 80 % del contenido inicial de la solución (1x 10-4 M), con la ventaja de que se pudo reutilizar la misma membrana en tres ciclos sin pérdidas apreciables de
dc.description.abstractWe synthesized a new organic polymer whose characteristics allow it to act as an extracting agent for metal ions. Membranes were made from polyvinylchloride (PVC) and 2 nitrophenyl octyl ether plasticizer (NPOE) together with the synthesized polymer and were used to extract gold from aqueous solutions of the metal. Additionally, we added sodium tetraphenylborate (Na-TFB) to improve the ion exchange between the working solution and the manufactured membrane. We determined the composition and membrane thickness showing the highest percentage of gold extraction, as well as the material selectivity towards Au3 + in the presence of other metal ions (Cu2+, Pb2+, Ca2+, Zn2+, Fe3+, Ni2+, and Al3+), each with an initial concentration of 1.4x10-4 M. The results showed percentages close to 80% of the initial content of the solution (1x10-4 M) extracted in one cycle; besides we were able to reuse the same membrane during three cycles without appreciable losses of efficiency.eng
