Abstract
A method for purifying dye-containing wastewater based on a porous-polymer-modified metal carbon nanotube membrane includes: (1) preparing the porous-polymer-modified metal carbon nanotube membrane; and (2) passing the dye-containing wastewater through the porous-polymer-modified metal carbon nanotube membrane to remove dyes in the dye-containing wastewater. A device for purifying dye-containing wastewater is also disclosed. The device includes the porous-polymer-based metal carbon nanotube membrane.
