Silver nanoparticle behaviour in lake water depends on their surface coating

JIMENEZ-LAMANA, Javier, SLAVEYKOVA, Vera. Silver nanoparticle behaviour in lake water depends on their surface coating. Science of the Total Environment, 2016, vol. 573, p. 946-953

Summary:

The growing use and concomitant release of a variety of silver nanoparticles (AgNPs) with different sizes and surface coatings into aquatic systems is raising concerns about their environmental fate and potential impacts. Given the low concentrations of engineered nanomaterials in the natural water, the studies of their fate requires the use of the most sensitive analytical techniques. In the present work, we use a combination of an asymmetric flow field-flow fractionation (AsFlFFF) and single particle inductively coupled plasma mass spectrometry (SP-ICP-MS) to characterize the behaviors of AgNPs of two different sizes and three coatings in lake water. Among the studied variables surface coating was found to play the major role of determining AgNPs behaviour in lake water.
