【 摘 要 】

Polybrominated diphenyl ether as an additive bromine flame retardant is widely used in industrial products, due to its strong fat-soluble and biological accumulating, it is a new type of ecological risk of environmental organic pollutants, and thus, resulted in more and more serious and widespread pollution. In view of the increasingly severe environmental conditions, this paper selected decabromodiphenyl ether(Deca-BDE) as the research object, based on the limited research data, taking its flame retardant mechanism as the starting point, and preliminarily discussed how the photodegradation of organic pollutants when Deca-BDE coexisted with other organic pollutants was affected by Deca-BDE. The experimental results show that, when ten Deca-BDE coexist with organic pollutants, the signal strength of organic pollutants photodegradation produce free radicals decreases, the preliminary judgment is Deca-BDE have a shielding effect on free radical signal, or Deca-BDE curbed the photodegradation of organic pollutants, lead to degradation of intermediate reduction, to detect the radical signal intensity weaken. Of course, there are still many areas for improvement and improvement in this study, which need to be proved by further research methods. This study is expected to provide guidance for the scientific classification and treatment of organic pollutants.
