| Abstract: | 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. |
