Equilibrio de intercambio iónico en el ablandamiento de agua con resinas sulfónicas en forma sódica

Abstract

Se ha esttrdiado el equilibrio de intercambio iónico Ca2+/Na+ con resina sulfónica (IMAC C-12) y en disoluciones de salinidad (0,010 N de Ca2+ y 0,019 N total) análoga a la del agua potabilizada de Barcelona procedente del rio Llobregat, cuyo análisis se efecfuó diariamente a lo largo del año 1978. Los resultados se discuten mediante análisis no lineal con diversos modelos de equilibrio, siendo la isoterma empírica de Rothrnund-Kornfeld y el modelo de Donnan los que mejor se ajustan, en contraste con lo inadecuado de la isoterma empírica de Freundlich y, sobre todo, del modelo de Langmuir, lo que permite explicar el equilibrio de intercambio a la luz de las hipótesis del modelo de membrana y no como fenómeno de adsorción superficial.
