硫含量是2–乙基蒽醌质量要求中需要严格控制的一项重要指标。通过实验对偏压范围、测试时间、转化率、积分电阻等因素进行研究和讨论,对测定2–乙基蒽醌中硫含量的实验条件进行了优化,建立了2–乙基蒽醌中硫含量的测试方法。该方法有很高的精密度,方法的标准偏差<0.15,回收率为94.5%~101.1%。
Sulfur content is an important indicator of 2-ethyl anthraquinone quality requirements that need to be strictly controlled. Experiments were carried out to study and discuss the bias range, test time, conversion rate, integral resistance and other factors. The experimental conditions for the determination of sulfur in 2-ethylanthraquinone were optimized. The sulfur in 2-ethylanthraquinone Content of the test method. The method has high precision, the standard deviation of the method <0.15, the recovery rate of 94.5% ~ 101.1%.
