The invention discloses a detection method for determining organic amine in ambient air and waste gas. The detection method comprises the following steps: S1, collecting a sample; S2, adopting an experimental instrument under experimental conditions; S3, treating the sample; and S4, establishing a working curve: preparing a standard sample curve according to the sample treatment process in the step S3, introducing samples according to the sequence of concentrations from low to high, and establishing the working curve by taking the concentration mg/L of the standard series as an abscissa and the corresponding chromatographic peak area as an ordinate. According to the invention, the detection limits of monoethylamine, diethylamine and triethylamine in ambient air are 0.1 mg/m , 0.2 mg/m and 0.2 mg/m respectively, the detection limits of monoethylamine, diethylamine and triethylamine in stationary pollution source waste gas are 0.2 mg/m , 0.3 mg/m and 0.3 mg/m respectively, the adding standard recovery ranges of
