Název v původním jazyce

Contribution to vapor generation-inductively coupled plasma spectrometric techniques for determination of sulfide in water samples

Popis výsledku v původním jazyce

Vapor generation inductively coupled plasma optical emission spectrometry was used for the determination of sulfide in water samples preserved by the addition of a zinc acetate and sodium hydroxide solution. Hydrogen sulfide and acid volatile sulfides were transformed, by acidification, to a gaseous phase in a vapor generator and subsequently detected by inductively coupled plasma optical emission spectrometry. Compounds interfering with iodometric titration and spectrophotometric determination were examined as potential chemical interferents. The proposed method provides results comparable to iodometric titration in the tested concentration range 0.06 to22.0 mg L 1. Limit of detection for the determination of hydrogen sulfide by this method is 0.03 mgL 1.
