| Abstract: | The analysis methods are studied here for using the nitric acid-hydrogen peroxide to decomposed the mineral rock samples and using the ICP-AES method to measure the total sulphur content.The varied conditions for decomposing the samples are inspected,and by selecting the suitable instrument working conditions and measurement lines,the interference of the matrix element is eliminated,with the detection limit of the method being 7.7×10-6.Through testing and verfying by a variety of the mineral rock samples,it is found that the results are in accordance with the standard requirements.The method is simple and rapid in operation,so it is suitable for the measurement of large quantities of the samples. |
