  • Purification of hydrogen sulfide-containing groundwater by hydrogen peroxide

    The advantages and disadvantages of reagent methods for cleaning groundwater from hydrogen sulphide are considered. The time of contact of hydrogen peroxide with hydrogen sulphide contained in the treated water was determined experimentally before the appearance of opalescence caused by the formation of colloidal sulfur. The equation for the time dependence for the start of the hydrogen sulfide oxidation reaction with the concentration of H2O2 is obtained, which makes it possible to calculate the required contact time of the treated water with hydrogen peroxide at a different content of hydrogen sulfide in the initial water.
