Preparation, separation and purification method of decabromodiphenylethane debromination product

The invention discloses a preparation, separation and purification method of a decabromodiphenylethane debromination product, and relates to the technical field of compound separation and purification. The method sequentially comprises the following steps: preparing a decabromodiphenyl ethane photodegradation sample; and detecting, separating, preparing, weighing and measuring the purity of the debrominated conversion product. Based on a decabromodiphenylethane photodegradation experiment and aiming at the characteristic of weak polarity of a debrominated degradation product, a high performance liquid chromatography-atmospheric pressure photoionization-time-of-flight mass spectrometry (HPLC-APPI-TOF/MS) combined semi-preparative liquid chromatography (SP-HPLC) technology is adopted for the first time, and the debrominated decabromodiphenylethane debrominated compound is analyzed through mass spectrometry and separation condition optimization, so that the debrominated decabromodiphenylethane debrominated compo
