摘要: 分光光度法与计算数学结合同时直接测定多组分体系已有多种方法,其中以经典方程组法,最小二乘法等应用较多[1],这些方法一般将吸光度与浓度之间的关系看作线性,且假设吸光度具有加和性.

Abstract: Anonlinear equation set method for simultaneous determination of multicom-ponent systems is presented. The method was applied to the inorganic colored systems which severely deviate from the Beer's law. The data processing was carried out by matrix calculation.Two-demonstrations of ..determination with this method are given and their results are satisfactory.
