| 摘 要： | 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，经氧气流高浊氧化为二氧化硫，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。

| Abstract: | The determination of total sulfur content i n BaCO 3 by burn volumetric analysis is introduced.The S with various valence i n the sample are oxided into SO 2 in the present of catalysts,Fe and Sn,further into H 2SO 3 by absorption liquid,then the H 2SO 3 obtained is titrated by I 2-starch titrant.Based on the consumption of the titrant,the total S content can be calculated.This method has the features of simple,quick,accurate and rea sonable. |
