Özet
A new potentiometric sensor for the determination of iodide based on poly(3-aminophenylboronic acid) (PAPBA) film electrode was constructed. Poly(3-Aminophenylboronic acid) films were synthesized electrochemically on platinum electrode by cyclic voltammetry. The effect of film thickness, pH, and preconditioning parameters on the electrode performance were examined. The analytical performance was evaluated and linear calibration graphs were obtained in the concentration range of 10(-6) to 10(-1) M iodide ion. The limit of detection was found to be 8 x 10(-7) M. The response time of the sensor was 5s and its lifetime is about one week. To check the selectivity of the PAPBA film for iodide ion, potential interferences such as Cl-, Br-, F-, CN-, IO3-, Ca-2(+), and Mg-2(+) were tested. The PAPBA electrode was also employed as a sensing platform for the determination of iodide ions in commercial table salt. (C) 2010 Elsevier B.V. All rights reserved.
