差示-双波长分光光度法及其应用

Differential Dual Wavelength Spectrophotometry and Its Application

将差示法和双波长法的优点相互结合，以用于对高浓度双组分的分析，在对苯酚和对苯二酚的测定中，方法的相对误差在２．３％以内，回收率为９７．８％～１０２．３％．

High concentration phenol and p dihydroxybenzene can be determined by the method which combines the differential spectrophotometry and dual wavelength spectrophotometry. The relative error of the method is less than 2.3% and the recovery is between 97.8% and 102.3%.
