Abstract
Compositions for the adsorptive removal of methyl tertiary butyl ether (MTBE) from contaminated water sources and systems. The compositions contain carbon fly ash doped with silver nanoparticles at specific mass ratios. Methods of preparing and characterizing the adsorbents are described. The composition may contain carbon acid-treated fly ash particles that consist of carbon, oxygen, and sulfur, and have silver oxide nanoparticles present on the surface and in pore spaces of the carbon acid-treated fly ash particles. The composition may be in the form of particles having sizes in a range of 100 nm to 2.5 μm with a BET surface area of at least 16.789 m/g, and contain the carbon acid-treated fly ash particles and the metal silver oxide nanoparticles at mass percentages of 50-90% and 10-50%, respectively.
