碘离子对B-Z振荡反应的影响及其应用 EFFECT OF. ION ON THE BELOUSOV-ZHABOTINSKII OSCILLATORY REACTION 安从俊 An Congjun Fang Xian’an Liu Yi Lin Zhixin Cai Ruxiu 1 first-author 方贤安 1 刘义 1 林智信 1 蔡汝秀 1 武汉大学化学系 武汉大学化学系 Department of Chemistry,Wuhan University Department of Chemistry,Wuhan University 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. 振荡反应 I-测定 抑制机理 oscillatory reaction I-determination inhibition mechanism O643.12;O657.15 1993-04-01 2021-04-01 4
