A macrocyclic vic-dioxime (1) and its mononuclear Ni(II) complex (2) were studied as extractant. The aqueous solutions of Ag+, Mn2+, Pb2+, Ni2+, Cu2+, Cd2+, and Zn2+ picrates were used for extraction experiments. The solutions of the ligands in two different organic solvents were used as organic phases. The metal picrate extractions were carried out at 25 +/- 0.1 degrees C by using UV-visible spectrometry. The most effective transport was observed for Ag+ picrate among the tested metal picrates. The effect of pH on the extraction of Ag+ picrate was evaluated with the ligands. The ratio of extracted Ag-complex to chloroform phase was 2:1 (L:M) for (2). In other cases the ratios were 1:1 for both (1) and (2). Molar ratio method was also used to demonstrate the composition. The values of the extraction constants (log K-ex) were determined for the extracted Ag-complexes.
