Verfahren zur Herstellung von Trennmaterialien

摘要

The invention concerns a method which is intended in particular to reduce the concentration of ions in separating materials when used in electrochemical processes, in particular in lead storage batteries. According to the invention, the separating material is subjected to a treatment with at least one acid selected from the group comprising sulphuric, phosphoric or sulphonic acid and/or with at least one salt selected from the group comprising sulphates, phosphates or diphosphates of the alkali or alkaline earth metals.
