Determination of Low Sulfur Content in Organic Compounds and petroleum products Using the Double Combustion method

摘要

A low content of sulfur (0.001wt%) was first determined in nitrobenzene and model mixtures of diesel fuel or benzene with n-decane,and the sulfur content of sodium sulfonates was also measured.A possibility for turbidimetric detection was shwon.The method has an almost unlimited use and is suitable for the analysis of subtances regardless of their physical state (combusible gases,gasolines,crude oils,residual oils,bitumens,rubbers,polymers).Variation in the sample mass form approx 5 mg to 6000 mg makes it possible ot determine elements at their low content (approx 10ppm) with no upper limit.The total time of analysis is 10-25 min.
