目前,国内外定量测定有机物中硫的方法较多,如“石油产品试验方法”中的GB380-64(燃灯法),GB387-64(管式炉法),GB388-64(氧弹法),SYB2606- 60(容量法)等。这些方法手续都比较复杂,每次测定需数小时。应用较普遍的三角瓶燃烧法,因其采用的是在静态氧气中燃烧吸收的方法,一次测定至少也需90分钟。另一缺点是在分析含有金属的试样时,燃烧生成的金属氧化物往往干扰硫的测定。美国D ASTM1552的快速高温燃烧法,虽然采用了较为复杂的高温炉等,但由于用淀粉作指示剂和碘化钾溶液为吸收液,
At present, there are many methods for quantitative determination of sulfur in organic compounds at home and abroad, such as GB380-64 (lamp method), GB387-64 (tube furnace method), GB388-64 (oxygen bomb method) in “Test Methods for Petroleum Products” , SYB2606- 60 (volume method) and so on. These methods are more complex procedures, each measurement will take a few hours. The more common trigonal flask combustion method, because it uses the method of combustion absorption in static oxygen, a determination of at least 90 minutes. Another disadvantage is that in the analysis of metal-containing coupons, the metal oxides produced by combustion often interfere with the determination of sulfur. The United States D ASTM1552 rapid high temperature combustion method, although the use of a more complex high-temperature furnace, but the use of starch as an indicator and potassium iodide solution as absorbent,
