燃烧-碘酸钾滴定法是目前测定大多数合金中硫的最普遍采用的方法。此法简单迅速,但准确度较差,不适宜做低硫的测定。现行测定合金中低含量硫(0.00x％)较准确和灵敏的方法有燃烧-碘酸钾滴定法、比色法及重量法。除前者可用于日常分析之外,后两者准确度虽高但手续都较烦琐,不易掌握,易受条件限制。电导法定硫,虽有报导,但研究 Combustion - potassium iodate titration is currently the most commonly used method for the determination of sulfur in most alloys. This method is simple and rapid, but the accuracy is poor, not suitable for low-sulfur determination. The most accurate and sensitive method for determination of low sulfur in alloys (0.00x%) is combustion - potassium iodate titration, colorimetry and gravimetric methods. In addition to the former can be used for routine analysis, the latter two are high accuracy but the procedures are more cumbersome, difficult to grasp, subject to conditions. Conducted statutory sulfur, although reported, but research
