Scope

Main technical content: The document specifies the gas chromatography-mass spectrometry determination method for three aniline compounds in water, namely o-toluene diamine, o-phenylenediamine, and 3,3'-dichlorobenzidine. This document is applicable to the determination of o-toluene diamine, o-phenylenediamine, and 3,3'-dichlorobenzidine in groundwater, surface water, domestic sewage, and industrial wastewater. When the sampling volume is 1000ml, the concentration volume is 1.0ml, and the full scan mode is used for determination, the method detection limits of o-toluene diamine, o-phenylenediamine, and 3,3'-dichlorobenzidine are 0.01g/L, 0.35g/L, and 0.04g/L, respectively.
