天然气中总硫的测定采用微库仑滴定法。此法应用高温氧化的原理,能将各种形态硫转化成二氧化硫和少量三氧化硫,通过库仑滴定测定总硫含量,是分析天然气中总硫较好的方法,但微库仑定硫仪的测定条件是较难控制的。因此,就微库仑滴定法的测定条件作了一些实验,为更好地掌握微库仑分析技术提供参考。 Determination of total sulfur in natural gas using microcoulometry titration. This method applies the principle of high temperature oxidation, which can convert various forms of sulfur into sulfur dioxide and a small amount of sulfur trioxide. The total sulfur content is determined by coulometric titration, which is a better method for analyzing total sulfur in natural gas. However, the determination of microcoulometry sulfur analyzer Conditions are more difficult to control. Therefore, some experiments on the determination conditions of microcoulometric titration have been done to provide reference for better understanding of microcoulometry.
