A flow injection configuration is proposed for the speciation and determination of thallium (I)
and thallium (III) in aqueous media by spectrofluorimetric detection. Thallium (I) can be
determined by measuring its fluorescence as TlCl32−. Thallium (III) also is determined after
the rapid reduction of this ion by hydrazine into thallium (I). The construction of a suitable
value in the manifold allows the successive determination of these ions at concentrations as
low as 10− 7M. The effect of potential interfering species on the determination was studied ...
