高频红外吸收法快速测定锌精矿中硫含量的研究

Research on the Rapid Determination of the Content of Sulfurin Zinc Concentrates by High Frequency Infrared Absorption Method

采用高频红外吸收法快速测定锌精矿中的硫含量。探讨了称样量、五氧化二钒和锡粒用量对硫分析结果的影响,对实际样品平行测定相对标准偏差均小于0.50%,测定锌精矿标准物质,结果一致。该方法具有精密度高、准确度好、简单、快速的优点。

This paper intruduces rapid determination of the content of Sulfur in Zinc concentrates by high frequency infrared absorption method.The influence of the the sample quality,vanadium pentoxide and tin grain quality to the analysis results were discussed.The relative standard deviation of the actual samples were less than 0.50%.The determination results of Zinc concentrate standard material is consistent with the normal.This method has the advantages of high accuracy,good accuracy,simple and rapid.
