摘要
Hexaacetatocalix(6)arene was used for the solvent extraction of iron(III). About 7.5 x 10(-2) M extractant was used at pH 7.0 for the quantitative extraction of iron(III). The metal from the organic phase was stripped with 1.0 M hydrochloric acid and determined spectrophotometrically as its thiocyanate complex at 480 nm. Iron(III) was separated from large excesses of alkali and alkaline earths in the ratio 1.20. The transition and main group elements were tolerated in the ratio 1:10. The method was extended for the analysis of iron from its mineral, alloy and pharmaceutical preparation. The method is reproducible with SD +/- 1.10%. (C) 1998 Elsevier Science B.V.
