摘要
从转化率和温度等方面对微库仑滴定技术测定芳烃溶剂中的硫含量的方法进行了优化。结果表明,采用优化的微库仑滴定法可以在芳烃溶剂中准确的测定小于1 ng/μL样品的硫含量,该方法操作具有简单、快捷、准确的特点,可以很好的应用于芳烃溶剂中硫含量的测定。
From the aspects of conversion rate and temperature etc, method for determination of sulfur content in aromatic hydrocarbon solvent by micro coulometric titration technique were optimized. And using the optimized micro coulometric titration for aromatic solvents, the sulfur content of the sample less than 1 ng/μL could be accurate determinated. The results showed that the method could be well applicated in determination of sulfur content in aromatic hydrocarbon solvent, and has the advantages of simple, fast, accurate.
