A preparation method of a high-performance electrode material for circulating water with high concentration ratio operation

Abstract

The invention relates to a preparation method of a high-performance electrode material used for high-concentration ratio operation of circulating water. The steps are as follows: disperse and suspend graphite powder in deionized water; add multi-wall carbon nanotubes; prepare the required solution; 2 solution and ReCl 2 The solution was dropped into the mixture; then PtCl was added dropwise 4 solution; add NaOH solution to the mixture until the pH reaches 9; add ammonia water to the mixture until the pH reaches 10, and cool the mixture to room temperature to clarify; suck out the supernatant and wash the reaction product until the pH of the eluate drops to 7.5; Add deionized water to the reaction product and stir; add the prepared NaBH to the mixture 4 solution, and the mixture is cooled to room temperature for clarification; the mixture is suction filtered; the filter cake is placed in an oven to dry; high-performance electrode materials are obtained, which can be formed by pressing. High-performance electrode materials are used for circulating water treatment, which can ensure the low-cost and high-concentration ratio operation of the circulating water system.

Description

technical field [0001] The invention relates to the development and application of a high-performance electrode material used for high-concentration rate operation of circulating water, in particular to the preparation and application of a high-performance inert electrode material. Background technique [0002] The water consumption of the circulating water system usually accounts for more than 70% of the water consumption of thermal power enterprises and iron and steel enterprises, and the amount of sewage generated is relatively large. Under the situation of increasingly stringent environmental protection requirements, the treatment of circulating water and sewage is facing huge environmental pressure. Therefore, the development and application of the high concentration ratio operation technology of the circulating water system is of great significance to the water saving and emission reduction of the circulating water system, such as the Chinese patent application number ...
