Abstract

The AlOOH/Cu modified cellulose acetate fibres were prepared by a facile one-step method. First, the cellulose acetate fibres were treated in an aqueous suspension with the bimetallic Al/Cu nanoparticles, followed by their oxidation. Copper and copper intermetallides do not react with water, while the aluminum does with boehmite formation. During this process AlOOH/Cu particles consisting of boehmite nanosheets self-assembled into flower-like agglomerates, and copper-rich fragments with size of 2 nm were formed. These inclusions could be spread uniformly through the whole volume of nanosheets or form a solid spherical copper-rich core in the center of AlOOH/Cu particles. The AlOOH nanosheets provide an adhesive attachment of the particles on the surface of the cellulose acetate fibres, and the slow migration of copper ions through the shell into the surrounding medium. The morphology, physical and chemical properties of the materials were characterized by transmission electron microscopy, scanning electron microscopy, X-ray diffraction, energy dispersive X-ray spectroscopy, adsorption of nitrogen (BET method), Fourier transform infrared spectroscopy and electrophoretic mobility (ζ-potential measurement). The antibacterial activity of the hybrid fibrous sorbent prepared against Escherichia Coli and Staphylococcus Aureus was studied. Reduction of the concentration viable bacteria reached 100 % after exposure of the bacteria for 1 h to the hybrid fibrous absorbent.
