• , solvents as acetonitrile and benzene, and contaminants as polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), organochlorine pesticides, dioxins, nitroaromatic derivatives, and many others. All these compounds are inadequate to interact strongly with silver, but could be captured by

These molecules, which normally do not interact with silver, could be effectively adsorbed on silica nanoparticles. UV–visible absorption spectra of colloidal silica (A
