Abstract
The invention relates to a method and a device for producing diluted hydrofluoric acid using an electrode arrangement (), which has an anode chamber () with an anode () and a cathode chamber () with a cathode (), which are separated from one another by an anion exchange membrane (), wherein in the method—pure water is guided through the anode chamber (), —pure water, which includes at least one electrolyte which forms fluoride ions (F−), is guided through the cathode chamber (), —and an electrical voltage is applied between the anode () and the cathode () such that the fluoride ions (F−) are moved through the anion exchange membrane () into the anode chamber (), and an electrical current flows.
