Özet

The purpose of this study is the development of a novel strategy for the determination of Al3+ ions using the combination of dispersive liquid-liquid microextraction (DLLME) and UV-Vis spectrophotometry. The method is grounded in the complexation between a novel antipyrine-based Schiff base reagent (EHMP) and Al3+ ions. Aluminum concentrations were detected using UV-Vis spectrophotometry at 260 nm and this technique was optimized using the absorbance value of EHMP-Al complex. pH, mixing period, type and volume of organic solvent, etc. were optimized stepwise in order to find out optimum experimental conditions. The limit of detection and the limit of quantification values for the improved analytical method were to be estimated 0.31 and 1.03 mu mol.L-1, respectively. The new strategy was successfully performed to define Al3+ ions in natural water samples with RSD values (84.01-107.71%) and recovery values (0.01-0.09%).
