微库仑法与紫外荧光法测定煤化工产品中总硫含量的对比

Comparison of total sulfur content in coal chemical products by microcoulometric method and ultraviolet fluorescence method

阐述了测定煤化工产品中总硫的两种不同方法,即紫外荧光法和微库仑法。通过对两种方法的原理,实验方法,样品测定的步骤及精密度等方面进行比较,结果表明紫外荧光法操作更简单、更环保、更高效,可用于煤化工产品中总硫含量的测定。

The paper illustrates two different methods for measuring the total sulfur in coal chemical products, namely the ultraviolet fluorescence method and the microcoulometric method.By comparing the basis, testing method, steps of the sample measurement, and precision and the like, the result shows that the ultraviolet fluorescence method is simpler, more environmentally friendly and more efficient, and it can be used in the measurement of total sulfur content in coal chemical products.
