Preconcentration of Trace Metal Ions by Coprecipitation with Gallium Phosphate for Flameless Atomic Absorption Spectrometry

Abstract

Gallium phosphate was a useful coprecipitant for the preconcentration of lead(II), tin(IV), antimony(III), and bismuth(III) on the flameless atomic absorption spectrometry. The determination of trace amount of lead(II) in water was demonstrated.

Use of Yttrium Phosphate as a Coprecipitant for Separation/Concentration of Lanthanoids

“…We have studied the coprecipitation of elements with metal phosphates, and have also applied the coprecipitation method to the separation/concentration of elements, including Pb, [14][15][16][17][18][19][20][21] Sn(IV), 22 In, 23 Cr(III), 24 Fe(III), 15,20,21 Bi, 15 and Cd, 25 for their atomic spectroscopic determination.…”
