适用范围：The method consists in extracting the acid from an acidified test portion using diethyl ether, nitrating followed by reduction and Mohler's reaction modified with hydroxylaminehydrochloride, measuring the absorbance of the red complex obtained with a suitable spectrometer. For determining lower concentrations, see ISO 5518.
