“…Further experiments showed that centrifugation at 2000 rpm had a similar particle selectivity as filtration through a 3 μm filter. Similar results were found 83 during the determination of silver NPs in tap and surface waters and sewage effluent. The recovery of NPs from surface water samples spiked with 60 nm diameter silver NPs increased from 60% for a 0.22 μm filter to 90% for a 0.8 μm polyethersulfone membrane filter.…”
This review covers advances in the analysis of air, water, plants, soils and geological materials by a range of atomic spectrometric techniques including atomic emission, absorption, fluorescence and mass spectrometry.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
