Abstract
A method for the determination of total sulfur in mineral oils has bee n developed. The method involves combustion of an oil sample in a pipe furnace in a stream of air at 1000 degrees C in the presence of CuO a nd spectrophotometric determination of the formed sulfur dioxide by pa rarosaniline method. The method can be used to determine from 2 to 50 mu g of sulfur in a 40 mg sample of oil. The linearity range of the me thod is 2-50 mu g S.
