The present work investigates the rapid and precise extractive method for the determination of aluminium(III) with hexaacetato calix(6)arene. Toluene, xylene and cyclohexane were found to be the best diluents for quantitative extraction of aluminium(III). In this study, aluminium(III) was extracted at pH 5.0 by equilibrating ten min with 10 mL of 1 x 10-4 M acetyl derivative of calix(6)arene in toluene. Aluminium(III) was stripped quantitatively with 1 N hydrochloric acid and determined photometrically by complexation with eriochrome cynine-R at 535 nm. The method affords the binary separation of aluminium(III) from associate elements. The stoichiometry of the extracted species was determined on the basis of slope analysis method. The temperature dependence of the extraction equilibrium was examined by the temperature variation method and the thermodynamic functions ∆H, ∆G and ∆S were also evaluated for the extraction process. The metal loading capacity was also evaluated. The proposed method was applicable to the analysis of real samples. The results obtained were reproducible and accurate.
