Study on the determination of the total sulfur by Coulomb titration method international inter laboratory studies
WANG Qiu-xiang
Abstract：Based on international standard proposal of Solid mineral fuels - determination of total sulfur in coal by titration method, the research experiment of international inter laboratory studies were done, the analysis and research for experimental data were done, so the precision of this method could be determined, and the accuracy could be evaluated.It was shown that: the determination result of this method and the classic Eschka method have no significant bias, the precision and accuracy could all meet the requirements, so the scientificalness of this international standard proposal and adaptability internationally could be proved.
