Airborne Silica and Titanium Dioxide Nanoparticles: Collection with Aqueous Surfactant or Chemical Reagent

Silica (SiO2) and titanium dioxide (TiO2) nanoparticles are widely used in agricultural, cosmetic and medical products. However, sampling devices are not readily available to help environmental scientists assess the levels of these nanoparticles that have been emitted and released to air by various sources. In this work, airborne particulates were bubbled through water containing either a surfactant (sodium dodecyl sulfate) or chemical reagent (ammonium molybdate + asc... view more»
