Abstract: Disclosed is a method for simultaneous determination of particle size distribution, concentrations of nanoparticulate mercury (Hg-NPs) in natural soils. The method uses sodium pyrophosphate as the extractant, and allows quick extraction of Hg-NPs in the soil without dissolution or aggregation. In combination with spICP-MS determination, the method makes it possible to simultaneously determine the particle size distribution and concentration of Hg-NPs in the complex soil matrix, with accurate determination results.
