Method for reducing and degrading brominated flame retardants in liquid phase and soil

A method for reducing and degrading brominated flame retardants in a liquid phase and soil comprises the steps that ascorbic acid AA serves as an enhancer of zero-valent metal zinc ZVZ, and the brominated flame retardants in the liquid phase and soil are reduced and degraded through a ZVZ and AA composite system. Green and friendly ascorbic acid (AA) is introduced into a ZVZ reduction system; theZVZ/AA composite system can be used for efficiently and rapidly degrading BDE-47 in a liquid phase and soil and HBCD in the soil; by introducing AA, the agglomeration and passivation of ZVZ particlescan be effectively inhibited, compared with traditional nZVI and a single ZVZ system, BDE-47 and HBCD are better in degraded, and the de-bromination rate is higher. A ZVZ/AA composite new system, which is simple, convenient, feasible, mild in reactions, efficient and rapid, is provided, and has an improved oxidizing and biologically degrading performance on brominated flame retardants. 一种还原降解液相和土壤中溴代阻燃剂的方法，包括：以抗坏血酸AA作为零价金属
