摘要：

Conditions for the determination of total sulphur and disulphide/polysulphide in petroleum products are described. The sulphur is reduced by heating with sodium or Devarda's alloy under reflux with subsequent liberation of H2S and measurement of the chemiluminescent S2 emission intensity in a hydrogen-argon diffusion flame. The precision and accuracy are good. Applications to light distillates and waxy residues are discussed. © 1979.
