摘要
研究确定了钙铁线的缩分方式及溶解方法,并采用重铬酸钾和EDTA分别测定钙铁线中的钙和铁,再加权平均来测得其含量,其重现性良好。
This paper studied and confirmed the division mode of calcium, iron wire and its dissolution method, and determined the calcium and iron in calcium, iron wire respectively by using potassium dichromate and EDTA, then measured their contents by taking weighted average. This method has good reproducibility.
