| Abstract: | A new fluorometric method is reported for determination of trace phosphorus, arsenic and silicon, based on the ion complexes of phospho-,arseno-,and silieo-molybdic acid with rhodamine 6G formed in the presence of nonionic surfactant PVA quenching the fluorescence of rhodamine 6G. The fluorescence spectra of the phospho-, arseno-,and silico-molybdic acid-rhodamine systems, the optimal complexes forming conditions and the composition of these complexes have been investigated. The method has been used for the simultaneus determination of P,As and Si in copper based alloys without preseparation. |
