A novel method for H2S analysis in an industrial gas stream

In recognition of the acute need for accurate and fast technique to be practiced online, a new test procedure for determining the amount of H₂S in an industrial effluent has been practiced in this investigation. Hence, original experiments are realized at laboratory and industrial scale. H₂S concentration in the industrial gas is deduced by measuring the turbidity involved by the formed Cadmium sulfide (CdS) in the Cadmium acetate solution upon contacting with hydrogen sulfide. Results demonstrated that this method is perfect and can be considered as an economic alternative to the iodometric method actually adopted in the Tunisian Chemical Group (TCG) of Gabes.
