Abstract: The 1 :n+2 Kalman filter applied to the experimental data of neopolarography is presented in this paper. The program of it is simple, fast when executed and it doesn't occupy much of memory space. It filters the random noise from the signal and separates the capacitive current from the faradaic current effectively at the same time. The performance of 1 : 3 Kalman filter was evaluated under the controlled conditions. An experimental evaluation of 1 : 3 Kalman filter is presented as applied to the analysis of trace metal Cd(Ⅱ) by staircase sweep neopolarography. The method has been verified further by the application of the method to the staircase sweep neopolarography of Tl (Ⅰ), Pb (Ⅱ) and In (Ⅲ) ions. It can be seen that Kalman filter smoothing is particularly powerful in the processing of experimental data of neopolarography.
