Determination and influence factors of total sulphur in diesel fuel by tube furnace combustion-ion chromatography

To establish an analytical method for the determination of the trace sulfur in diesel fuel by tube furnace combustion-ion chromatography. Samples were burned through tubular furnace and oxidation of sulfur into sulfate ion in absorbent, which was measured by ion chromatography. The response was linear (r > 0.9995) in the range of 0.01 to 5.00mg/L and the limit of detection for the sulfate ion was 0.002mg/L. The application result showed that the recovery rate was higher than 95% and this validated method was successfully applied for the analysis of sulfur in diesel fuel. (paper)
