摘要
双波长分光光度法由于具有原理简单,测定点少,计算量小并能有效地克服一个或数个干扰组分的影响等优点,应用日益广泛。实现该方法的关键。
A dual- wavelength linear regression spectrophotometry was introduced and evaluated. The optimal wavelengths and calibration curve could be determined simultaneously depending on a group of standard mixture solutions by using linear regression method. The deviation of absorption resulting from molecular interaction could be calibrated by this method and the results were more accurate. The validity of this method was confirmed through its use in analysis of three-acid powder with a satisfactory result.
