  • METHODS FOR PREPARING FUNCTIONAL MEMBRANE FOR RECOVERING PRECIOUS METAL IONS FROM OILY WASTEWATER
    Publication number: 20250229232
    Abstract: A method for preparing a functional membrane for recovering precious metal ions from oily wastewater is provided. The method includes: obtaining carbon nanotubes functionalized by polyacrylic acid (CNTs-PAA) by grafting acrylic acid onto a surface of carbon nanotubes (CNTs) via graft polymerization; obtaining carbon nanotubes modified by acyl hydrazine functional groups (CNTs-PAH) by reacting adipic dihydrazide (ADH) with carboxyl functional groups of the CNTs-PAA; preparing single-layer MXene nanosheets using Ti3AlC2 powder; and preparing a CNTs-PAH/MXene composite membrane by vacuum filtration based on the CNTs-PAH and the single-layer Mxene nanosheets.
