Problems solved by technology
Although the Fenton reaction has strong oxidative properties and is widely used in a variety of industrial wastewater treatment, there are still some defects in this technology: the applicable range of pH is narrow; 2 o 2 Low utilization efficiency; large output of Fe sludge
However, most of them suffer from low stability and poor catalytic performance

The invention discloses a method for rapidly degrading bisphenol A in a water body, which relates to the field of degradation of organic pollutants in the water body, and specifically comprises the following steps: preparing trimetallic spinel ferrite nanoparticles, adsorbing the water body containing bisphenol A by the trimetallic spinel ferrite nanoparticles, adding hydrogen peroxide solution into the water body after ensuring to achieve the adsorption-desorption equilibrium, so as to complete the degradation process and subsequent recovery of trimetallic spinel ferrite nanoparticles. The degradation method of the invention effectively catalyzes hydrogen peroxide to generate hydroxyl radicals, so as to oxidize organic pollutants, the stable trimetallic spinel ferrite nanoparticle structure effectively prevents the exudation of iron and the precipitation of iron ions, therefore, the method can be applied to a larger pH range, and the free radicals with high oxidation potential generated by the system can also produce better treatment effect on other refractory organic matters except bisphenol A in water.
Description
technical field [0001] The invention relates to the field of degradation methods for organic pollutants in water bodies, in particular to a method for rapidly degrading bisphenol A in water bodies. Background technique [0002] At present, researchers have found that many natural or synthetic non-steroidal substances exhibit estrogenic activity. Chronic exposure to environmental estrogens can have large health effects, as estrogens affect reproduction and cellular development and may pose cancer risks. In recent years, bisphenol A (Bisphenol A, BPA), that is, diphenolic propane, has been used in various plastic products, and new applications have been continuously developed, resulting in the detection rate of bisphenol A in surface water and drinking water. It is high and has seriously endangered human health, so it is of great significance to develop an effective and practical method for removing BPA in water. [0003] At present, there are three ways to treat sewage cont...
