摘　　要：本文提出的“组合导数分光光度法”,是以双波长K-系数法作为多组分同时测定的数学模型,用于解析不同阶次的导数光谱数据。实验结果表明,该法可准确测定普通光谱和导数光谱均严重干扰的混合体系,且能显著提高分析灵敏度。The combined derivative spectrophotometry developed is a new method, which can be used for the simultaneous determination of multicomponent and may improve remarkably the sensitivity and the selectivity of the determination. Two practical tests were given to verify the theory and the results were satisfactory.
