title: Determination of total sulphur in fuel oils by molecular emission cavity analysis.
abstract: Molecular emission cavity analysis (MECA) is used for the determination of total sulphur in fuel oils. The sulphur is reduced by heating the sample with Devarda's alloy in an HCl medium, with subsequent liberation of H2S and measurement of the chemiluminescent S2 emission intensity in the MECA cavity. The total sulphur recovery from different sulphur-containing compounds and fuel oils is always ca. 100%. The precision and accuracy are good. Applications to certified and commercial fuel oils are discussed.
