Conclusions
-
1.
Results of the determination of microquantities of sulfur in petroleum products have been compared, obtained by a Raney nickel method and by combustion followed by nephelometric determination of sulfur as barium sulfate.
-
2.
These data show good agreement of the results of both methods obtained on synthetic blends as well as on petroleum products.
-
3.
The combustion followed by nephelometric determination of sulfur allows determination of sulfur concentrations down to 5·10−5%. The method allows also the determination of sulfur in products with high contents of unsaturated hydrocarbons and in highly viscous products (oils, etc.).
