Nanomaterial Dispersion/Dissolution Characterization: Scientific Operating Procedure SOP-F-1
Abstract
Evidence suggests that a materials dispersion and dissolution behaviors may be crucial to understanding the materials environmental risk. Since exposure risks are directly determined by the environmental fate of nano silver (nAg), extensive efforts have been put forth in elucidating the behavior of these materials in natural systems. Thus, it is important to understand the different metrics that can be used to represent nanoparticles (NPs) in a system. Given the connection between a materials dispersion and dissolution kinetics, a protocol is presented to measure the dissolution kinetics of nanomaterials using a simple 48-hour experimental protocol that utilizes environmentally representative waters as well as non-destructive analytical techniques. Protocols for the simultaneous measurement of the nanoparticle dispersion properties are also presented. When used with the appropriate equations listed in this scientific operating procedure, data derived from these simple experiments can provide fundamental information about the behavior of nanoparticles in different environments.
