Abstract

Desionización o desalación de grafeno perforado. Procedimiento para la desionización de agua portadora de iones no deseados, cuyo procedimiento comprende las siguientes etapas: disponer una hoja de grafeno con múltiples aberturas seleccionadas para permitir el paso de moléculas de agua e impedir el paso de un ión seleccionado de dichos iones no deseados; someter a presión dicha agua portadora de los iones no deseados para generar de esta manera, agua a presión; aplicar dicha agua a presión a una primera superficie de dicho grafeno perforado, de manera que las moléculas de agua pasan a un segundo lado de dicha hoja de grafeno perforado con preferencia a los iones; y recoger dichas moléculas de agua de dicho segundo lado de dicha hoja de grafeno.
