The electrochemical behavior of catechol, hydroqulnone and resorcinol on GCand PPy/GC electrode surface were studied by CV and RDE method. The results in-dicated that these three substances could be oaldized electrocattwtically on PPy filmelectrode. The possibility of fabrication of amperomtric electrochemical sensor for cate-chol was also studied.
