Photometric Determination of Total Sulfur Content of Coal with Barium Chromate
摘 要
收集氧弹法测定煤的发热量后弹筒内的残渣和残液,用铬酸钡光度法进行比色分析,实现煤中全硫的测定.方法的测定结果与重量法结果吻合,回收率在99%~104%之间.
Abstract
Total sulfur in coal was determined by the BaCrO4 photometry.The ash and solution remained in the oxygen bomb after determination of calorific value of coal were collected and used as the sample solution for sulfur determination.The results obtained were in consistency with the results obtained by gravimetry.Values of recovery found were in the range of 99%-104%.
