Simultaneous sulfur dioxide absorption and hydrogen sulfide generation in aqueous solution of sodium sulfide
Article Abstract:
A method for absorbing sulfur dioxide while simultaneously generating hydrogen sulfide in aqueous sodium sulfide is presented. It is shown that aqueous Na2S can effectively absorb SO2 in flue gas and generate H2S during the second stage. The system exhibited a three-stage pattern, with the pH of the solution changing with the amount of SO2 absorbed by the Na2S solution. Incomplete conversions of sodium sulfide were observed.

Oxidation of hydrogen sulfide in aqueous solution by ultrasonic irradiation
Article Abstract:
The utilization of ultrasonic irradiation for the oxidation of hydrogen solution in oxic aqueous solutions over a range of applied power is discussed. Sulfide ion specific electrode were used to measure sulfide concentrations. Sonification, sample withdrawal and multiple analysis were used for the kinetic runs. It was found that rapid oxidation will result from the ultrasonic irradation of hydrogen sulfide in water.

Nucleophilic substitution reactions of dihalomethanes with hydrgen sulfide species
Article Abstract:
The effect of alkyl halide structure on reactivity is discussed. The reactivities of bisulfide ion hydrogen sulfide and negative ion hydroxide were compared within a series of dihalomethanes, as gas chromatography analysis was also performed. Results indicate that dihalomethanes reactions with hydrogen sulfide produces highly significant toxicological outcome in comparison to their parent compound.
