正交回归试验法通常用于科研和生产中的实验和生产条件的优化。我们将该方法应用于混合稀土中的组分分析,得到较满意的结果。本文是继前面的工作,用新合成的灵敏显色剂——对马尿酸偶氮氯膦体系,进行多波长下多因子的回归正交实验,用以分析混合稀土中的组分含量。原理王保宁等采用多波长数据的线性回归法测定两个干扰组分。应用同一波长下各干扰组分吸光度的线性加和性,建立各波长下的回归方程,通过解联立方
Orthogonal regression test method is usually used for scientific research and production optimization of experimental and production conditions. We apply this method to the composition analysis of mixed rare earths and get more satisfactory results. This is the previous work, with the newly synthesized sensitive reagent - on the hippuramine hippurate system, multi-wavelength multi-factor regression orthogonal experiment for the analysis of mixed rare earth components. Principle Wang Bao-ning and other multi-wavelength data using linear regression method for the determination of two interference components. The linear additivity of the absorbance of each interfering component under the same wavelength is used to establish the regression equation of each wavelength.
