| Abstract: | This paper carried on the research analysis to the influence conditions on determi- nation of sulfur content in petroleum products by using different microcoulomb titrinuter. （KY2000, LC- 6, RPA100）. Having analysed the influence of different prepared electrolytes with different brands of potassium iodide , acetic acid indicated that the quality of potassium iodide, acetic acid was the primary factors leading to low conversion rate . This paper also discussed the effects of determination of different concentrations of sulfur content in petroleum products by electrolytes prepared without sodium azide ,and de reasons of several fault phenomena. |
