Asymmetric flow field-flow fractionation of manufactured silver nanoparticles in soil pore water

Research output: Contribution to conferenceAbstractAcademic

Abstract

Manufactured silver nanoparticles (AgNP) are among the most widely used nanoparticles in consumer products and their unintended release to soils has become a serious concern. For a meaningful assessment of the environmental risks of AgNP in soils, their concentration and particle-size-distribution in soil pore water need to be measured. This can be done by using asymmetric flow field-flow fractionation (AF4), which is an analytical technique for the continuous fractionation of nanoparticles as a function of their diffusion coefficient. We will present results of a study focussing on the development of a methodology consisting of AF4 in combination with UV-Vis spectroscopy and HR-ICP-MS to quantify the concentration and particle-size-distribution of AgNP coated with either citrate or polyvinylpyrrolidone in soil pore water obtained from three soils with contrasting properties.
