摘　　要： 研究了络合吸附催化不可逆体系受前行化学反应控制（Ｋ　１）和不受前行化学反应控制（Ｋ　１）两种情况下的循环叠式方波伏安法的电流理论，并进行了实验验证，讨论了电流特性，获得区分Ｋ　１和Ｋ　１的判据。对于上述体系的测定，循环叠式方波伏安法的灵敏度比普通差式采样方波伏安法高一个数量级以上。 The theoretical potential-current and peak-potential equations of additive cyclic square wave voltammetry have been dervied for coordination-adsorptive catalytic irreversible systems either controlled by the rate of coordination reactions(K1)or not controlled by the rate of coordination reactions (K1).The current characteristics were investigated in details,and the criterion for the determination of K1 or K1 has been obtained.The results of experimental verification were in accord with the theoretical conclusions.For the above irreversible systems, the sensitivity of additive cyclic square wave voltammetry is about one order of magnitude higher than the conventional square wave voltammetry.
