| description | <p dir="ltr">Novel activated carbon (AC) composite materials, namely AC doped with aluminum oxide (Al<sub>2</sub>O<sub>3</sub>) and AC doped with Al<sub>2</sub>O<sub>3</sub> and silver (Ag) nanoparticles, have been prepared via a one-step thermal decomposition method. The developed composite materials were used to study the adsorptive removal of molybdenum (Mo) and arsenic (As) from contaminated water. Several techniques, including X-Ray diffraction (XRD), transmission electron microscopy (TEM), scanning electron spectroscopy (SEM), energy dispersive X-Ray spectroscopy (EDS), and thermal gravimetric analysis (TGA), were used to characterize the synthesized materials. TGA results show that the material is very stable and decay starts only above 450 °C. The effects of pH on the adsorptive removal of As and Mo on AC-Al<sub>2</sub>O<sub>3</sub> have also been studied. The prepared AC-Al<sub>2</sub>O<sub>3</sub> material showed 94% removal of total As at pH of 6% and 97% removal of Mo at pH 2. The pollutants removal is due to electrostatic attraction and ligand exchange adsorption mechanisms. It was also found that the novel AC-Al<sub>2</sub>O<sub>3</sub>-Ag composite materials exhibit notable antibacterial properties towards both Gram-negative (<i>Escherichia coli</i>) and Gram-positive (<i>Bacillus subtilis</i>) bacteria.</p><h2>Other Information</h2><p dir="ltr">Published in: Journal of Alloys and Compounds<br>License: <a href="http://creativecommons.org/licenses/by/4.0/" target="_blank">http://creativecommons.org/licenses/by/4.0/</a><br>See article on publisher's website: <a href="https://dx.doi.org/10.1016/j.jallcom.2020.158372" target="_blank">https://dx.doi.org/10.1016/j.jallcom.2020.158372</a></p> |
