| 摘 要： | 研究并确定了氧弹燃烧—BaSO4重量法测定柴油中硫含量的燃烧条件、吸收液种类、沉淀溶液pH、沉淀和转移条件等实验条件。在实验确定的优化条件下，该方法的定值结果与其他方法吻合良好。对定值结果进行了全面的不确定度评定，对于硫含量0．515％和1．027％的柴油中标准物质，获得的展伸不确定度分别为1.3％、1.4％(K=2)。利用该方法成功地实现了较低含硫量样品的定值。 |

| Abstract: | This paper describes the certified reference materials sulfur in diesel oil determination by Barium Sulfate Gravimetry after oxygen bomb combustion.The experiments conditions,such as combustion condition,the kinds of absorbing liquid,pH of precipitate and the condition of transition precipitate,were studied.Under optima conditions,the result of determination of sulfur by this method was good with other three methods.The extend uncertainty were1.3%and1.4%(K=2)for content of sulfur0.515%and1.027%respectively.The method was applied to the determination of lower content of sulfur in sample satisfactory. |
| Keywords: | Oxygen-bomb-combustion Barium Sulfate Gravimetry diesel oil Sulfur reference materials |
