Abstract: The invention relates to a method for electrolytically decomposing hydrogen sulfide dissolved in an amine scrubber solution in an electrolysis cell (11), which comprises an anode chamber (9) and a cathode chamber (15), wherein the anode chamber (9) and the cathode chamber (15) are separated by a membrane (13), wherein at least one conducting salt is added to the amine scrubber solution, an anion-conducting membrane is used to separate the anode chamber (9) and the cathode chamber (15), and/or the amine scrubber solution in which the hydrogen sulfide is dissolved contains at least 10 vol.% potassium-N,N-dimethylamino acetic acid. The invention further relates to a use of the method.
