摘要
铬元素的含量是影响硬质合金品质的一个重要参数,生产中要求对其准确的测定和控制,本文提出一种新的测定方法——铬酸比色法。即将试样中铬元素氧化为Cr(Ⅵ),排除干扰后再进行比色测定。
The concentration of Cr is a important factor influencing the quality of hard alloy, so it is necessary to determine and control its concentration in production. This paper, introduces a new method to analyse the content of Cr in alloy, which is to oxidate Cr to Cr6+ after eliminating interferences, and determine it by spectrophotometry.
