Embodiment Construction
[0013] A method for potential oxidation degradation of organic pollutants of the present invention, the powdered battery material and acetylene black are mechanically mixed and ball milled, then pressed into tablets, and assembled into a battery as a positive electrode material, charged to 3-4.2V, and then charged to 3-4.2V The final electrode material is taken out and soaked in an organic pollutant solution, and the preparation method is carried out according to the following steps:
[0014] a. Mechanically mix and ball-mill the powdered battery material and carbon at a mass ratio of 20:1 to 8:1 for 2-20 hours, and then press into tablets, wherein the thickness of the tablets is 0.1-0.2cm;
[0015] b Use the sheet pressed in step a as the positive electrode material, assemble it into a battery, and charge it to 3-4.2V;
[0016] c. Disassemble the battery charged to 3-4.2V through step b, take out the electrode material prepared in step b, and place it in an organic pollutant ...

Abstract
The invention provides a method for potential oxidation degradation of organic pollutants, which belongs to the field of organic pollutant degradation, and comprises the following steps: firstly, mechanically mixing and ball-milling powdered materials together with acetylene black, and then pressing them into tablets, and assembling them as positive electrode materials The battery is charged to 3-4.2V, and then the charged electrode material is taken out and immersed in an organic pollutant solution to oxidize and degrade the organic matter. The method for degrading the organic pollutant of the present invention is simple and easy to operate.
Description
technical field [0001] The invention relates to a method for potential oxidation degradation of organic pollutants, which belongs to the field of degradation of organic pollutants. [0002] technical background [0003] Since entering the 21st century, energy and the environment have increasingly become major issues to be solved urgently for future human beings. Organic pollutants continue to grow. These organic substances are difficult to degrade in the natural environment and have a very long residence time. They can be ingested into the human body through the respiratory tract and digestive tract, and may also be absorbed into the human body through the skin, affecting the oxygen supply of tissue cells and causing internal suffocation. Some categories are even carcinogenic, posing a serious threat to human survival, reproduction and sustainable development. In recent years, the degradation of organic pollutants has attracted great attention, and how to further improve the...
