摘要
石硫合剂中的多硫化钙分析,本文提出亚硫酸钠法,该法标准偏差为0.04,变异系数为0.14%,与重量法比较测定结果基本一致.
Anew method to analyse calcium polysulfides in lime sulfide by using sodium sulfite was reported in this pa-per. The results were satisfactory to meet the request of pro-ductioii with standard deviatioh 0.04,coefficient of raviation0. 14%.
