[0103]1) Cut the original carbon fiber cloth into a 3.5cm diameter circle, and use a mixture of 10% nitric acid and 10% sulfuric acid solution (nitric acid: sulfuric acid volume ratio 3:1) to perform Soak, after 30 minutes of ultrasonic treatment, react for 48 hours in a thermostat at 50°C. After the solution is cooled, wash it with ultrapure water several times to remove surface residues and impurities until the pH of the washing solution is neutral, and then at 40 Fully dry it in a vacuum oven at ℃ until it reaches a constant quality, then the modified carbon fiber cloth is obtained;
[0104]2) Arrange the above modified carbon fiber to soak in ultrapure water, then add 0.4mol / L Fe(NO3)3·9H2O and 0.2mol / L Cu(NO3)2·3H2O, ultrasonic for 1 hour to mix uniformly and completely dissolve to obtain a mixed solution, and add ammonium fluoride and urea to it, continue to stir, and then place it in a cons...
[0106]1) Cut the original carbon fiber cloth into a 3.5cm diameter circle and take 1.5mL 30wt% H2O2And 97mL ultrapure water in a 250mL Erlenmeyer flask, and adjust the pH to 3, then add 1.5mL 0.2mol / L Fe2+Solution (may be ferrous sulfate or ferric chloride solution), soak the carbon cloth, after 30 minutes of ultrasonic treatment, react for 48 hours in a thermostat at 50°C, and wash with ultrapure water after the solution is cooled Several times, remove the surface residues and impurities until the pH of the washing solution is neutral, and then fully dry it in a vacuum oven at 40°C until it reaches a constant quality to obtain a modified carbon fiber cloth;

Embodiment 3
[0109]The difference from Example 1 is that the mixture of 10% nitric acid and 10% sulfuric acid solution (volume ratio of nitric acid: sulfuric acid is 3:1) is replaced with 0.3mol / L hypochlorous acid , Others are the same as in Example 1.

Abstract
The invention discloses a ferrite modified carbon fiber cloth electrode and its preparation method and application, comprising the following steps: 1) preparation of modified carbon fiber cloth; 2) preparation of ferrite material modified carbon fiber cloth electrochemical cathode. The invention also discloses the ferrite material modified carbon fiber cloth electrode and its application. The modified carbon fiber cloth electrochemical cathode modified by the ferrite material can be used in an electrochemical / ozone coupling water treatment system. The preparation method has convenient raw materials, simple preparation process, low cost, high catalytic activity and superior electrode performance, and is a water treatment technology with low energy consumption, high efficiency and complete mineralization of pollutants. The electrochemical cathode of the modified carbon fiber cloth modified by ferrite prepared by the invention has broad application prospects in degrading persistent organic pollutants (POPs) in a cycle electric filtration system.
Description
Technical field[0001]The invention belongs to the field of advanced sewage treatment, and specifically relates to a ferrite modified modified carbon fiber cloth electrode and a preparation method and application thereof, and particularly relates to the use of ferrite modified modified carbon fiber cloth electrochemical cathode and carbon fiber cloth anode in electrochemical / ozone coupling The application of the system to degrade POPs pollutants.Background technique[0002]The sources of POPs in the water environment are mainly through the following two ways: one is the incomplete removal of domestic sewage, industrial wastewater, and hospital wastewater containing higher concentrations of POPs into natural water bodies such as rivers and lakes through sewage treatment plants; the other is agriculture, The direct discharge of wastewater from animal husbandry and aquaculture or underground infiltration makes POPs enter the water environment. Due to the wide range of POPs components and ...
