“…Such an extensive use raises questions about its safety, environmental toxicity and the risks associated with microbial resistance and cross-resistance. 3,5 Silver is considered to be toxic to humans and the recommendations of the World Health Organization (WHO) permit a maximum concentration of 0.1 mg L À1 of silver in drinking water disinfection, but the United States Environmental Protection Agency (USEPA) recommends 0.05 mg L À1 as the maximum. Thus, the determination of low concentrations of silver is of increasing interest.…”

This review presents a comprehensive update on the state-of-the-art of nanometer-sized materials in solid-phase extraction (SPE) of trace elements followed by atomic-spectrometry detection. Zero-dimensional nanomaterials (fullerene), one-dimensional nanomaterials (carbon nanotubes, inorganic nanotubes, and nanowires), two-dimensional nanomaterials (nanofibers), and three-dimensional nanomaterials (nanoparticles, mesoporous nanoparticles, magnetic nanoparticles, and dendrimers) for SPE are discussed, with their application for trace-element analysis and their speciation in different matrices. A variety of other novel SPE sorbents, including restricted-access sorbents, ion-imprinted polymers, and metal-organic frameworks, are also discussed, although their applications in trace-element analysis are relatively scarce so far.
