Photothermo-catalytic water purification method

Abstract

The application relates to the technical field of water purification, and discloses a water purification method based on photo-thermal catalysis, which comprises the following steps: performing ultrasonic cleaning operation on bamboo fiber materials by using a first cleaning solution to obtain clean bamboo fibers; respectively performing impregnation and drying operation on the clean bamboo fibers by using carbon nanotube solution and nitrogen-doped carbon nanotube solution to obtain carbon nanotube modified bamboo fiber fabrics and nitrogen-doped carbon nanotube modified bamboo fiber fabrics; preparing a metal ion solution by using cobalt nitrate hexahydrate and copper nitrate trihydrate; reacting the metal ion solution by using a thiourea and ethylenediamine active agent to obtain a brown solution; and preparing first and second composite photo-thermal catalyst bamboo fiber fabrics by using a pre-constructed polytetrafluoroethylene-lined high-pressure kettle, the brown solution, the nitrogen-doped carbon nanotube modified bamboo fiber fabrics and the carbon nanotube modified bamboo fiber fabrics to construct a water purification device to purify water sources. The main purpose of the application is to improve the water purification efficiency.
