Method for detecting N, N '-ethylene bis (tetrabromophthalimide) in plastic

The invention provides a method for detecting N, N '-ethylene bis (tetrabromophthalimide) in plastic, and relates to the technical field of detection and analysis. The invention provides a plastic with N, N-dimethyl formamide. The detection method comprises the following steps: putting a plastic sample into a proper organic solvent, extracting under a certain condition, determining an extract liquid by using a gas chromatograph-mass spectrometer, establishing a standard working curve, and analyzing and calculating N, N '-ethylene bis (tetrabromophthalimide) in the plastic sample to obtain N, N'-ethylene bis (tetrabromophthalimide). According to the method for detecting the content of the flame retardant N, N '-ethylene bis (tetrabromophthalimide) in the plastic, which is established by the invention, the pretreatment operation is simple and convenient, and the detection method is low in impurity peak interference, high in sensitivity, high in result accuracy and good in precision. 本发明提供了一种塑料中N,N'-乙撑双四溴邻苯二甲酰亚胺
