AI Technical Summary

Problems solved by technology

However, the high resistance and low conductivity of traditional electrode materials lead to low current efficiency, insufficient stability, short life, and high cost of electrode materials in wastewater treatment, which limits the application and development of electrocatalytic oxidation technology in water treatment. , so the research and preparation of new electrode materials need to be further strengthened
At present, there is still a lack of electrode materials and preparation methods with high-efficiency electrocatalytic removal of furan-specific pollutants

Abstract

The invention discloses a modified quartz particle electrode with a function of removing furan through electrocatalysis and a preparation method thereof. Quartz, trichloromethane and ethyl alcohol are prepared into a substance A; the substance A is prepared into a substance E through modifying mixed liquid prepared from silver nitrate, platinum nitrate, diethyl ether and Bi(NO3)3; the substance E is prepared into a substance H through modifying mixed liquid prepared from Pb(NO3)2, ethyl alcohol, CeCl3, ZrCl4, MgCl2 and CdCl2; the substance H is prepared into a substance K through modifying mixed liquid prepared from lauryl sodium sulfate, normal hexane, normal butanol, ammonium metavanadate, sodium citrate, MgCl2 and CdCl2; the substance K is prepared into a substance through modifying mixed liquid prepared from polyvinyl alcohol and HAuCl4, and the substance is the modified quartz particle electrode with the function of removing furan through electrocatalysis.

Description

technical field [0001] The invention belongs to the technical field of electrocatalytic oxidation treatment of refractory organic wastewater, and in particular relates to a modified quartz particle electrode with the function of electrocatalytically removing furan and a preparation method thereof. Background technique [0002] Electrocatalytic oxidation technology is a very promising water treatment technology that has gradually developed in recent years. It mainly oxidizes and degrades organic pollutants in wastewater by generating hydroxyl radicals and other active groups with strong oxidizing properties. Refractory organic matter or biotoxic pollutants are converted into biodegradable or non-toxic substances, improving the biodegradability of wastewater, thereby facilitating subsequent biological treatment. Therefore, the electrocatalytic oxidation water treatment technology has the characteristics of no secondary pollution, low cost, strong applicability, and high effici...
