石灰石中硅铁铝钙镁的全部分析,过去一般都采用经典法。近一、二年来随着生产发展的需要,我们对钙镁的测定采用了EDTA络合滴定法。(1)但对于硅及少量铁铝的快速测定仍未能采用,今年来,我们在党的领导下,在全民大跃进的鼓舞下,我们全组的同志开动了脑筋,把石灰石的硅铁铝钙镁的全分析工作全部改成了快速测定,大 Limestone in all the analysis of silicon iron aluminum calcium and magnesium, the past generally use the classic method. Nearly one or two years with the needs of the development of production, our determination of calcium and magnesium using EDTA complexometric titration. (1) However, the rapid determination of silicon and a small amount of iron and aluminum still can not be adopted. This year, under the leadership of the party and encouraged by the great leap forward of the entire nation, our comrades in our group have started their own brains and put ferrosilicon Al-Ca-Mg full analysis of the work into a rapid determination of large
