Sorption X,Ray fluorescent determination of iron (III), zinc and mercury (II) on ÊU,2 kation exchanger modified by dye rhodamine G

Zauer E.A.

 Sorption concentration conditions of mercury (II), zinc and iron (III) ions from aqueous solutions in the form of thiocyanate anionic comples on ÊU,2 kation exchanger modified by dye rhodamine G has been optimized with subsequent direct analysis of granulated concentrate's surface using X,ray fluorescence "Spectroscàn" spectrometer. This procedure may be applied for monitoring of content of these elements in native and waste water.

Keywords: X,ray fluorescence analysis, sorption preconcentration, dye rhodamine G, thiocyanates anionic complexes of iron (III), zinc and mercury (II)
