Abstract
A filtration membrane including a first layer having a triamine-functionalized copper oxide polysilicate mesoporous material, a second layer including a polysulfone, and a third layer including a polyester terephthalate. The triamine-functionalized copper oxide polysilicate mesoporous material includes a copper oxide polysilicate backbone and a silicon atom of a silicon-containing triamine bonded to a silicate group in the copper oxide polysilicate backbone. The copper oxide polysilicate backbone is datively bonded to one or more tetramines, and the silicon-containing triamine and one or more tetramines are covalently cross-linked with terephthaloyl chloride to form a polyamide.
