Abstract

The sorption of Pd(II), Au(III) by phytosorbent FS-744 on the basis of sawdust, modified by phosphate and primary amino groups was studied. Sorbents FS-744 quantitatively extracts ions of gold(III) and palladium(II) under 1-4 M hydrochloric acid. The equilibration time is less then 10 minutes. The selectivity of sorbent FS-744 to gold and palladium ions at the presence of non-ferrous and heavy metals was studied. Desorption of noble metal ions is carried out by 5 % thiourea solution. The technique of sorption-atomic-emission determination of gold and palladium, including sorption concentration, elution sorbed elements and their definition in the desorbed solution was developed.
