摘要
研究了不同[I^-]对 B-Z 振荡反应的影响及其在分析测试中的应用.结果表明,I^-是 B-Z振荡反应较强烈的抑制剂,加入 I^-经过诱导期后第一个振荡周期的振幅改变值ΔA与[I^-]有良好的线性关系,线性范围为1×10^(-5)～1.8×10^(-3)mol·L^(-1),是一个重现性好,灵敏度高的动力学分析测试体系,最后,结合 FKN 机理考察了 I^-对振荡反应的影响.
In this paper,effect of [I^-] on the Belousov-Zhabotinskii oscillatory reaction and application in I^- determination was studied.Result shows that I^- is strong inhibitors on the Belousov- Zhabotinskii oscillatory reaction,added I^- passes after a induce period,the amplitude decrease of first oscillatory period has good linear relationship with [I^-],linear range is 1.0×10^(-5)～1.8×10^(-3) mol ·L^(-1).It is a kinetic analytical determination method of good veproducibility and high sensitivity. finally,effect of I^- on the Belousov-Zhahotinskii oscillatory reaction was discussed according to FKN mechanism.
