Abstract: According to the effect of pH on the maximum response current im of the poly-aniline uricase electrode, the plot of log im versus pH shows that the catalytic activity of the uricase electrode is only related to the dissociated group in the base form. The results of the scanning electron micrograph indicate that the stability of the uricase electrode is influenced by its preparing method. The uricase electrode formed by electrochemical immobilization has a high stability over 121 days.

Key words: Immobilization of uricase, Polyaniline uricase electrode, Catalytic activity, Stability and morphology
