Description
Summary:	A novel ceramic-polymer composite nanofiltration membrane was fabricated using in-situ generated Cu nanoparticles by dip coating over modified ceramic support tube. The prepared membrane was used for Cd (II) removal from contaminated water. Generation of in-situ Cu NPs on/in the membrane was characterized by SEM and XPS analysis. Incorporation of NPs formed by in-situ chemical reduction technique improved the pore size of modified ceramic substrate towards NF range (~1 nm). The positively charged composite NF membrane exhibited satisfactory performance with respect to pure water permeability (8.09 L m−2 h−1 bar−1) and Cd(II) rejection of 95.5%.
