The invention relates to a method for degrading a brominated flame retardant, in particular to a method for degrading a brominated flame retardant by adopting a polyethylene glycol/alkaline method. Under a mild condition and in the presence of an aid, polyethylene glycol/alkaline serving as a nucleophilic reagent is reacted with the brominated flame retardant to generate aryl ether polyethylene glycol and aryl ether alcohol, then aryl ether polyethylene glycol generates aryl ether alcohol by heating, and thus the purpose of degrading the brominated flame retardant is achieved, wherein the reaction is specifically shown as the formula in the specification. The method has the advantages that the efficiency is high, the reaction condition is mild, the reaction product is easy to treat, the operation is easy to control and the cost is low.
