| 摘 要： | 采用控制电位下的线形扫描方法，在H2O2与高氯酸、盐酸或硫酸及其相应阴离子的盐组成的体系中、考察了不同浓度配比时的电化学振荡行为。结果表明，H2O2和H^ 浓度是产生电化学振荡的主要因素。EQCM的测量结果证明了阴离子在铂电极表面发生吸附，在较负的电位范围发生脱附。据此，讨论了不同阴离子的吸附对电化学振荡行为的影响。

| Abstract: | The electrochemical oscillation behavior of the system consisiing H_2O_2,acidic solution(such as HClO_4,H_2SO_4 and HCl)and its related salt have been investigated with Linear Scanning Voltanmmtry(LSV).The effects of various concentrations of H_2O_2 and H~+ on oscillation have also been discussed.The frequency increased due to the desorption of anion from the electrode has been observed when scanning more negative potential With EQCM.It proves that specific adsorption of anion on the electrode occurs. |
