Abstract
The influence of experimental conditions on the Chromatographic behavior and separation efficiency of iron(III) and gold(III) in partition paper chromatography was investigated, when solvents containing diisopropyl ether (IPE) were used. The influence of temperature (range investigated from 15 to 50 °C), initial acid concentration (1–11 M HCl), and concentration of active solvent component (0.7–7.1 M IPE, benzene as diluent) on the R f values were particularly studied. Ascending technique using Whatman No. 1 paper was employed. Considerable influence of temperature was found. The best separation (Δ R f = 0.26) was achieved with 9 M concentration of hydrochloric acid and 3.6 M (50% volume) concentration of IPE.
