用四氧化三锰加硫酸的方法制备不同含硫量的管理样

Prepared Different Kind of Management Sample with Mn₃O₄ Adding Sulphuric Acid

摘要: 采用向Mn₃O₄中加入已知浓度的硫酸，制备不同硫含量的Mn₃O₄、MnO₂、MnSO₄的混合物管理样，将制备的混合物处理之后，用高频红外碳硫仪进行分析. 结果表明，所得结果与实际含硫量基本相吻合. 对硫管理样进行XRD分析，结果表明，硫管理样中的MnSO₄含有结晶水，并由此得出碳硫仪测定结果与实际硫含量相符的原因.

Abstract: Different sulfur content mixtures of Mn₃O₄, MnO₂, MnSO₄ was prepared by adding known concentration sulfur acid to Mn₃O₄. The prepared mixtures was analysed with high-frequency infrared carbon-sulfur. The tested data indicate that the percentages of sulfur in those mixtures are in line with the true. XRD analysis result shows that because MnSO₄ contains crystallization water, the data of sulfur tested by high-frequency infrared carbon-sulfur are equal to the really value.
