【摘要】 某混合物含三种组分，且均与某试剂作用，根据吸光度及化学计量比推知三组分的总含量后，不需分离，按一定规则选取两个波长，测其吸光度，用朗伯－比尔定律及代数法、图解法，可获得三元混合物各组分含量．更多还原

【Abstract】 Each component in a ternary mixture reacts with a reagent, the total concentration will be known by the absorbance and chemical stoichiometric ratio. And then, the determination of the three components is able to be finished by measuring the absorbance at two wavelengths, using the primary algebraic and graphic method without separation.更多还原
