| Abstract: | 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. |
