Separation and preconcentration of platinum group metals and gold on modified silica and XAD sorbents in the presence of cationic surfactants for their determination by ICP-AES

Popis výsledku v původním jazyce

Various modified silica sorbents and bare silica were tested for the separation and preconcentration of 10 - 200 ng cm-3 from 50 - 1000 cm3 sample volume of platinum group metals (PGMs), Pt(IV, II), Pd(II), Ir(IV), Rh(III), Os(VI), Ru(IV) and Au(III) inthe form of ion associates of their chloro and bromo complexes with cationic surfactants. (1-(ethoxycarbonyl)pentadecyl) trimethylammonium bromide (Septonex?), benzyl(dodecyl)dimethylammonium bromide (Sterinol?), trimethyl(tetradecyl)- ammonium bromide and hexadecyl(trimethyl)ammonium chloride are suitable from 0.1 mol dm-3 HCl or 0.1 mol dm-3 HBr. A 100% recovery for Pd(II), Pt(IV) and Au(III) was obtained with octadecyl silicas Separon? SGX C18, Separon? SGX RPS and Phenyl? silica in the presence of 0.006 mol dm-3 Septonex? or 0.003 mol dm-3 Sterinol?. The retained PGMs and Au(III) were eluted with acetonitrile and determined by inductively coupled plasma atomic emission spectrometry (ICP-AES) after evaporation of organic solvent in t
