"Direct Fluorometric And Flow Injection Fluorometric Methods For The Determination Of Trace Phosphorus"
Fenxi Ceshi Xuebao 1998 Volume 17, Issue 3 Pages 77-79
Song Gongwu, Feng Jian

Abstract: Direct fluorometric determination of trace P is based upon the quenching of the fluorescence of rhodamine 6G due to the formation of a nonfluorescent hetero-polynuclear acid of rhodamine-phosphoro-Mo ion-associates. The excitations wavelength is 350 nm, while the maximum emission wavelength is 555 nm. The flow injection fluorometric variant of this method has the advantages of high sensitivity, good selectivity and simplicity. It was satisfactorily employed for the determination of P in Cu alloys, steel, and Mn ores.
