摘要
交流示波极谱过去仅用于简单体系的测定,当溶液中含有大量干挠离子时,dE/dt～E曲线上将产生许多切口,它们互相重叠干扰,无法进行定量测定,本文首次将Kalman滤波算法引入交流示波极谱,用于解析多组分共存时的示波图,将重叠切口进行分离,使干扰共存时定量测定成为可能。
Kalman filter technique for the separation of overlapping incisions of a. c. oscillopo-larogram is presented. The experimental verifications were carried out in various systems with the ions of Pb2+, Tl+ , In3+ and Cd2+. The results show that the concentration of depolarizer can be determined directly and easily with this technique while other interference elements exist.
