介绍了燃烧容量法测定碳酸钡总硫含量的分析方法。试样中各价态的硫 ,在铁屑和锡粒催化下 ,经氧气流高温氧化为二氧化硫 ,经吸收液吸收变为亚硫酸。用碘—淀粉标准滴定溶液滴定 ,根据其消耗量计算出总硫含量。燃烧容量法与日本标准方法测定原理一样 ,测定结果一致 ,与日本标准方法相比 ,简便、快速、准确、合理 The method of analyzing the total sulfur content of barium carbonate by combustion volume method is introduced. The valence state of the sulfur in the sample, iron chips and tin particles under the catalysis, the oxygen flow into high-temperature sulfur dioxide, absorbed by the absorption liquid into sulfite. Titration with iodine - starch standard titration solution, according to its consumption to calculate the total sulfur content. The combustion volume method is the same as that of the Japanese standard method, and the measurement results are the same. Compared with the Japanese standard method, the combustion volume method is simple, rapid, accurate and reasonable
