摘要： 依据pH对聚苯胺尿酸酶电极最大响应电流的影响, logim～pH图表明尿酸酶电极的催化活性只与其电离基团的碱性形式有关. 扫描电镜的结果表明, 聚苯胺尿酸酶电极的稳定性与其制备方法有关. 电化学法固定的尿酸酶电极具有高的稳定性.

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.
