Voltammetric Determination of Anethole on La₂O₃/CPE and BDDE

Figure 10

Standard addition voltammograms (black) and the same curves after subtracting experimental background, and next simulated baseline approximated using 3rd degree polynomials (blue), in determination of the anethole in 0.1 mol L⁻¹ acetate buffer on La₂O₃/CPE, in (a) matrix D, (b) Ouzo, and (c) Raki. Each voltammogram set: background, sample, and 1.39, 2.78, 4.18, and 5.57 mg L⁻¹ standard additions of anethole.
