| titleOfInvention | Method for measuring content of sulfur in coal by utilizing energy chromatic dispersion X-ray fluorescence analysis |
| abstract | The invention relates to a method for measuring the content of sulfur in coal by utilizing energy chromatic dispersion X-ray fluorescence analysis, and mainly solves the problem that the sensitivity and the efficiency for detecting a sulfur element in the coal are low in the prior art. The method comprises the following steps of firstly pre-treating a coal sample, and preparing a standard sample and a test sample; measuring a barium element in the test sample by utilizing an energy chromatic dispersion X-ray fluorescence analyzer, detecting the fluorescent number of the barium element, and substituting the detected fluorescent number of the barium element in a calibration curve to obtain the percentage composition of the barium element in the test sample; and calculating the percentage composition of the sulfur element in the coal sample according to a chemical number relation between the sulfur and barium in the sample. The measurement of the sulfur content in the coal is realized by adopting an indirect measuring method. The method has characteristics of rapidness in measurement and easiness in operation. |
