Oxidation of hydrogen sulfide with hydrogen peroxide in natural waters

Studies on the effects of pH value (pH 2-8), temperature (5-45C), and ionic strength (0-6 M) on the oxidation of hydrogen sulphide with hydrogen peroxide in sea water and sodium chloride solutions are reported. Over the entire range of pH value and temperatures studied, ionic strength had little or...

Description
Summary:Studies on the effects of pH value (pH 2-8), temperature (5-45C), and ionic strength (0-6 M) on the oxidation of hydrogen sulphide with hydrogen peroxide in sea water and sodium chloride solutions are reported. Over the entire range of pH value and temperatures studied, ionic strength had little or no effect on the rate of oxidation. The rate of oxidation increased with increase in temperature and in pH value over the range 2-8, but decreased slowly at pH values greater than 8. The possible mechanism involved are considered.
