"Determination Of Phosphorus And Silicon In Carbon Steel And Low-alloy Steel By Flow Injection Analysis"
Yejin Fenxi 1989 Volume 9, Issue 3 Pages 30-33
Shen, Jihua; Miao, Fengqin

Abstract: The determination is based on the molybdenum blue method. The sample solution is treated with NH4F to eliminate the interference of ferric molybdate. The sample solution is used as the carrier flow and mixed with ammonium molybdate solution to form the heteropolyacid. After a fixed amount of reducing agent is injected, molybdenum blue forms for determination of phosphorus and silicon. The method is simple and rapid in analysis of carbon and alloy steel.
