Reaction time between copper power and samples was optimized according to the experimental conditions of ASTM-D-1275 (B) method, and then the total sulfur of each sample before and after the reaction with the copper power , and the sulfur content of reacted copper power were determined respectively. The precision of the three methods was compared by the linear regression r of the content of corrosive sulfur in standard sulfur sample. The results showed that the coulometric method was the most reliable methods of the three methods and the high-frequency infrared method would be applied to measuring the active sulfur in oil in the future.Keyw...
