Abstract: The present invention relates to a method for purifying a contaminant-laden current by bringing the current to be purified in contact with a heterogeneous photocatalyst and irradiating it with light, wherein it is brought into contact in the presence of at least one compound, which is dissolved in the current and contains at least one metal selected from the group consisting of iron, chromium, nickel, cobalt, manganese, and mixtures thereof, and to the use of a heterogeneous photocatalyst for purifying a contaminant-laden current, wherein at least one compound containing at least one metal selected from the group consisting of iron, chromium, nickel, cobalt, manganese, and mixtures thereof, is present in dissolved form in the current to be purified.
