Chitosan membrane development and design of equipment for the removal of heavy metals from water
A filtration technique with 1,75% m/v chitosan membranes crosslinked with glutaraldehyde (0,08% v/v) was used to quantify the removal capacity of chromium, copper and cadmium ions from water. A simple and low cost filtration system was developed to use with prepared membranes.The main goal was to us...

El presente estudio comparó la eficiencia de la filtración con membranas de quitosano 1,75% m/v, entrecruzadas con glutaraldehído (0,08% m/v) y sin entrecruzar, para estimar la capacidad de remoción de iones de cadmio, cromo y cobre de disoluciones modelo. Además, se diseñó un equipo de bajo costo para la experimentación con las membranas elaboradas. La finalidad de la investigación era emplear materiales biodegradables para remover metales pesados de aguas, mediante una técnica de bajo consumo energético y, por otra parte, generar soluciones baratas, efectivas y aplicables a problemas específicos. Se elaboraron dos fichas técnicas con información sobre las membranas y se encontró que el cromo fue el metal removido en mayor medida por las membranas entrecruzadas, ajustándose al modelo de isoterma de Freundlich. Sin embargo, no se encontró relación entre el tamaño de poro de las membranas y el grado de entrecruzamiento. 2012-11-19 2015-03-23T21:03:48Z 2015-03-23T21:03:48Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Artículo revisado por pares https://revistas.tec.ac.cr/index.php/tec_marcha/article/view/453 https://hdl.handle.net/2238/4287 spa https://tecdigital.tec.ac.cr/servicios/ojs/index.php/tec_marcha/article/view/453/381 application/pdf Editorial Tecnológica de Costa Rica Tecnología en Marcha; Vol. 25, Núm. 3 (2012) 2215-3241 0379-3982 |
