Abstract

The present application discloses a method of producing an aqueous rinsing liquid in an electrochemical cell having an anode chamber with an anode and a cathode chamber with a cathode, the anode chamber and cathode chamber being separated by a cation-selective membrane, wherein the method includes the steps of (a) feeding an aqueous anode chamber feedstock into the anode chamber (b) feeding an aqueous cathode chamber feedstock comprising at least one electrolyte through the cathode chamber; and (c) applying an electrical voltage to the anode and cathode to form rinsing liquid in the cathode chamber; and wherein steps a, b and c are performed, at least in part, simultaneously. Also disclosed is apparatus suitable for carrying out such methods.
