摘要
焦化硫膏总硫质量分数的分析目前还没有统一的方法标准。建立了艾士卡法测定焦化硫膏样品中总硫质量分数的分析方法。通过试验对操作条件进行了优化,通过对方法准确度、精密度的测试及比对试验,得出该方法操作周期虽长,但准确度高,精密度好,没有基质干扰,适用于焦化硫膏总硫质量分数的仲裁分析。
At present, there is no unified method standard for the analysis of total sulfur mass fraction in coking sulfur paste. In this paper, an analytical method was established to determine total sulfur mass fraction in coking sulfur paste samples by Eschkal method. Finally, the typical operation conditions were verified, and results showed that the method had good accuracy and precision. Although the operation cycle of the method was long, the accuracy was high and the precision was good, and there was no matrix interference. It was suitable for arbitration analysis of total sulfur mass fraction in coking sulfur paste.
