试样以浓硫酸溶解,加入还原剂将Sb()还原为Sb(),在盐酸介质中,以甲基橙为指示剂,用硫酸铈标准溶液滴定锑,锑()被硫酸铈氧化为锑(),以计算锑量。方法适用于0.5%以上锑量。该方法准确性高,可以准确测定锑矿石中的锑,适用于矿山,地质找矿过程中锑含量的测定。本文结合本实验室实际操作,对操作过程中的各个步骤中与其他实验室所用方法的不同之处进行一定的论述和讨论。
The sample is dissolved with concentrated sulfuric acid, Sb () is reduced to Sb () by adding a reducing agent, antimony is titrated with cerium sulfate standard solution in hydrochloric acid medium with methyl orange as an indicator, and antimony () is oxidized by cerium sulfate to antimony () To calculate the amount of antimony. The method is suitable for the amount of antimony above 0.5%. The method has high accuracy and can accurately measure antimony in antimony ore and is suitable for the determination of antimony in ore and geological prospecting process. In this paper, the actual operation of the laboratory, the operation of the various steps in the laboratory and other methods used in the differences between the certain discussion and discussion.
