Abstract

An amperometric detector based on the chemical modification of Nafion and indium (III) hexacyanoferrate (II, III) thin film (Nafion/In-CN-Fe) onto a glassy carbon (GC) electrode, was first successfully used for the determination of electroinactive cations (Li+, Na+, K+, Rb+, Cs+, NH4+) in single column ion chromatography (IC). A set of well-defined peaks of electroinactive cations was obtained. The detection limits of the cations are 8.9 x 10(-6) mol/L for Li+, 2.3 x 10(-6) mol/L for Na+, 5.2 x 10(-6) mol/L for K+, 4.8 x 10(-6) mol/L for Rb+, 4.0 x 10(-6) mol/L for Cs+ and 5.3 x 10(-6) mol/L for NH4+ at a single-to-noise ratio of 3. The proposed method was quick, sensitive and simple. The cations in rainwater and mineral water were successfully analyzed by this method.
