摘要： 将一种改进的目标因子分析法(MTFA)用于复杂反应的速差动力学分析体系,采用此法处理实验数据时,引入了一个非零截距因子,采用模拟纯谱运算。可使方法的准确度大大提高。据此建立了一种停流技术进样、速差动力学分析同时测定、因子分析处理实验数据的新方法;对于10-6mol·L-1级的肾上腺素-去甲基肾上腺素混合物,比例范围在1:5～5:1之间,测定相对误差小于±10%,用于合成样品中肾上腺素和去甲基肾上腺素的同时测定,获得了满意结果。

Abstract: Amodified target factor analysis(MTFA)method has been applied to differential rate kinetic system in which synergic effects are taken into account in this paper.Asimple differential kinetic method by stopped-flow and MTFA has been proposed.In the meantime,the optimum experiment conditions of oxidation of EPand NE with Fe(phen)33+were investigeted. This mehtod has been applied to the determination of two component EPand NE with satisfactory results. The accuracy the of method was greatly improved.
