| Description
| - Selective preconcentration of gold in the form of ion associates of Au(III) chloro complex or Au(I) cyano complex with quaternary bases was studied using modified silica gel. Solutions containing gold in the presence of the complexing anion and a quaternary base were pumped through a Separon(TM) SGX C18 column. After elution with 96 vol.% ethanol, the eluate was evaporated in the presence a complexing agent (chloride or cyanide). The resulting aqueous solutions were analyzed with inductively coupled plasma atomic emission spectrometry. The influence of concentration of onium salts, chlorides, nitrates, and the influence of the sample volume on the sorption were studied. The sorption flow rate and the elution volume were optimized, and the separation from a geological sample matrix was verified. The best recovery (100%) of preconcentration of Au(III) chloro complex was obtained with [1-(ethoxycarbonyl)pentadecyl] trimethylammonium bromide and 1-hexadecylpyridinium chloride at concentrations of 0.006 an
