- Determination of Sulfur in Heavy Oils by Fluorescent X-Ray Spectrometry
抄録
Samples are solidified with paraffin (mp 68-70C) to eliminate the effect of bubbles which decrease analytical precision. And the sulfur contents are analysed by the measurements of radiation intensity of sulfur.<BR>Standard samples are prepared by the dissolution of TTD (Tetraethyl Thiuram Disulfide) in melted paraffin and then solidified by cooling. Linear calibration curve is given for sulfur. The relative standard deviation of measurements for ten samples is about 1% and the coefficient of correlation for chemical analysis is 0.999.<BR>Solid samples are stable for repeated measurements.<BR>Time required for the analysis of one sample is about 20 minutes.
