Nano-TiO₂ powder prepared by sol-gel method was used to modify carbon paste electrode successfully.Optimum conditions for detection of trace indium at the modified electrode and the electrochemistry stability of the modified electrode were investigated by simultaneous cyclic voltammetry.There was a sensitive oxidation peak in the voltammogram at -0.832 V characteristic of trace indium in HAc-NaAc buffer whose pH was 5.4 when the accumulation time was 200 s and the potential scan rate was 200 mV/s.There was a good liner relationship between the peak current and In³⁺ concentration in a range of 1.0×10^-11~1.0×10^-9 mol/L with a correlation coefficient of 0.995,and the detection limit was 0.125×10^-11 mol/L.This proposed method was applied to the analysis of actual water samples and the average recovery was 96.16%.The oxidation process of indium was controlled by both charge transfer and diffusion at the modified electrode.This oxidation process of indium was irreversible,and its average activation energy was 72.36 kJ/mol.
