Abstract: <p>Silver nanoparticles (nAg) are the largest and fastest growing class of nanomaterials, and are a concern when released into aquatic environments even at low μg L<super>-1</super. levels. Measurement at environmental levels requires extremely sensitive instrumentation, therefore this research developed two passive samplers to track the the concentration of nAg and… more
Abstract: <p>A novel passive sampler for mercury monitoring was prepared using organosilica sol-gel materials. It comprises a binding layer with thiol groups for mercury complexation and a porous diffusive layer through which mercury can diffuse and arrive at the binding layer. Our study demonstrated that this new sampler follows the principle of passive sampling. The mass of mercury accumulated in… more
