Abstract

A flow injection analysis method for trace amount P(V) and As(V) determination has been established based on the fluorescence quenching effect of rhodamine 6G due to the formation of an unfluorescence ion-association complex. Rhodamine 6G has a maximum emission wavelength of 555 nm (excitation at 350 nm). The calibration curves were found linear in the range of 0-80 microg/L of P(V) and 0-100 microg/L of As(V). The method has been used for the determination of P(V) and As(V) in copper alloys with satisfactory results.
