【Abstract】 An anion-selective electrode based on 2,4-dihydroxybenzaldehyde-diaminodipropylamine (cobalt(Ⅱ)) metallic complex as a neutral carrier is reported. The sensor exhibits unique selectivity and high sensitivity toward iodide, which displays an anti-Hofmeister selectivity pattern. The response mechanism is discussed based on the AC impedance technique and the UV spectroscopy technique. The electrode can be applied to food analysis and the result is in fair agreement with the result given by spectrophotometry.更多还原
