With the continuous development of the global economy, the demand for fossil fuels such as crude oil and coal is increasing, and the emission of sulfur contained in these fuels has become one of the important sources of environmental pollution. Therefore, accurate measurement of sulfur content in fossil fuels is of great significance for environmental regulation and energy development.

In chemical analysis, the sulfur content of fossil fuels is measured, usually by coulometric titration. This method relies on the electrochemical properties of the sulfur species and uses electrochemical methods to determine the amount of sulfur in the sample. It is suitable for the analysis of high concentration of sulfur elements, and has the characteristics of rapid measurement and high accuracy. The operation steps of

coulometric titration mainly include the following links: the first step of

is to measure the quality of the sample, and under certain chemical conditions, the chemical reagents that lead to chemical reactions are gradually dropped into the sample;

the second step, the change of charge in the sample is measured by coulometer, and the sulfur content in the sample is determined by calculation.

the third step, the sulfur content of the sample is calculated from the measurement data and compared with the sulfur content of other fossil fuel products. The environmental impact is assessed accordingly.

coulometric titration has the characteristics of fast measurement, high accuracy, high precision and fast sample processing. Therefore, it is widely used in industry and scientific research, and has become one of the basic technologies for measuring the content of chemical elements. In addition, the method is also widely used in the field of environmental protection in the air, water pollution measurement.

Coulometric titration is an efficient and stable analytical method, which is not only suitable for the determination of elements, but also one of the important experimental methods in the field of chemical analysis. It plays an irreplaceable role in the analysis and detection of various sulfur-containing substances in the industrial and environmental protection fields.
