摘要: A reductive procedure for the determination of sulphur was modified and applied to analysis airborne particles. It is based on reduction given forms with mixture HI/HCOOH/H3PO2/Sb2O3 hy-drogen sulphide, which transferred into a NaOH solution determined by microtitration Cd2 + using dithizone as indicator. Examination behaviour different in showed that inorganic converted H2S whereas organic remained reaction flask. This makes possible differentiation between when one part sample directly reacted other oxidatively decomposed (Schoniger), then total same procedure. The method used number particle samples origin, results were compared those some instrumental techniques.
