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.
The effect of different [I ~ -] on BZ oscillation reaction and its application in the analysis and testing were studied.The results showed that I ~ - was the stronger inhibitor of BZ oscillation reaction, and the first The amplitude change ΔA of the oscillation period has a good linear relationship with [I ~ -], and the linear range is 1 × 10 ~ (-5) ~ 1.8 × 10 ~ (-3) mol·L ~ (-1) Reproducible and sensitive kinetic analysis test system. Finally, the influence of I ~ - on the oscillatory response was investigated in combination with the FKN mechanism.
