摘要
对KY200型、LC—6型、RPA100型微库仑滴定仪测定石油产品硫含量的影响条件进行分析研究,测试不同品牌批号的碘化钾、冰乙酸所配电解液对试验的影响,确认碘化钾和冰乙酸的质量是造成仪器转化率低的主要因素,文中还讨论在测定不同浓度硫含量的油品时,电解液中有无叠氮化钠对测定的影响,并针对几起故障现象分析了原因。
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.
