Abstract
Un método para purificar electroquímicamente soluciones con un pH a 14 para reducir, impurezas metálicas al nivel de trazas. El método comprende el procesado de una solucion en una celda electrolítica, en donde el cátodo tiene red fibrosa producida de una mezcla de fibras, incluyendo cuando menos una fraccion que consiste de fibras eléctricamente conductoras, y un aglutinador seleccionado de fluropolímeros, en donde la red fibrosa se deposita en un soporte poroso eléctricamente conductor. El cátodo también puede combinarse con un diafragma o membrana. También se revela un cátodo con una red fibrosa producida de una mezcla de fibra de carbon, compuestos de celulosa y un polímero cationico, como puede ser el almidon cationico.
