摘要：
Sorption of gold(III) chlorocomplexes was studied by means of a carbon paste electrode modified with montmorillonite. Anionic exchange behavior was found in chloride media with low ionic strength. Anionic sorption of [AuCl4]– can be used as a preconcentration step to the determination of Au(III). Linear calibration dependences were found in the concentration range 4.06 × 10–6– 1.22 × 10–5 mol/L Au(III) after 5 min of sorption and in the range 8.12 × 10–7– 6.1 × 10–6 mol/L after 10 min of sorption. Interferences of several anions and cations were studied. Model samples of table water were analyzed.
