一、引言近年已有许多作者论述了计算机在分析化学中的应用,但是探讨多组分混合物吸光度法的文章尚不多见。目前应用吸光度法,是将过量的有机试剂与欲测元素生成有色络合物,根据比尔定律构筑校正曲线来测定欲测元素。但是有机试剂与络合物的吸收曲线互相重叠且吸收峰间相距越小,则产生的误差就越大;另外,当 I. INTRODUCTION In recent years, many authors have discussed the application of computers in analytical chemistry. However, it is still rare to discuss the multi-component mixture absorbance method. Absorbance method is currently used, is the excess organic reagents and the elements to be measured to generate colored complexes, according to Beer’s law to build a calibration curve to determine the elements to be measured. However, when the absorption curves of the organic reagent and the complex overlap each other and the smaller the distance between the absorption peaks is, the larger the error is. In addition, when
