Preparation method of high-performance electrode material for high concentration rate operation of circulating water

Abstract

The invention relates to a preparation method of a high-performance electrode material for high concentration rate operation of circulating water. The method includes the following steps: dispersing and suspending graphite powder in deionized water; adding a multi-walled carbon nanotube; preparing a required solution; dropping a SnCl2 solution and a ReCl2 solution into the mixture; dropping a PtCl4 solution; adding a NaOH solution into the mixture until pH reaches 9; adding ammonia water into the mixture until the pH reaches 10, and cooling the mixture to room temperature for clarification; sucking a supernatant solution out, and cleaning a reaction product until the pH of an eluate is reduced to 7.5; adding deionized water into the reaction product and stirring the mixture; adding a prepared NaBH4 solution into the mixture and cooling the mixture to room temperature for clarification; pumping-filtering the mixture; placing a filter cake into a baking oven for drying; and obtaining thehigh-performance electrode material, and pressing the high-performance electrode material for forming. The high-performance electrode material can be used for treatment of circulating water and can ensure the low-cost high-concentration rate operation of a 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 ...
