摘要
以单个离子分析方法为基础,通过对已知物质的量浓度的模拟着色液的多次分析试验,建立了不锈钢酸性化学着色液主要成分的分析方法:用氧化还原滴定法测定Cr2O72-、Cr3+、Fe3+的含量,用吸光光度法测定Ni2+的含量。
Based on the methods of analyzing individual ions and multiple analysis tests on known concentration simulation solutions, the methods of analyzing main components of stainless steel chemical coloring solutions were established. The concentration of Cr2O^2- 7, Cr^3＋ and Fe^3＋ was determined by redox titration, and Ni^2＋ by absorption spectrophotometry.
