“…This value was much less than the Zeta potential threshold of colloid stability (±30 mV). 28 Therefore, the par-ticles could not effectively repel each other either by electrostatic or by steric force, and consequently they aggregated as shown in the TEM images (Images 1, 2, Figure 1). …”

Zero-valent iron particles were prepared by wet reduction chemistry assisted with ultrasonic treatment. Such prepared particles have uniform size, exhibit crystalline structure and show strong paramagnetic property. Their surface modification by coating poly(N-vinyl-2-pyrrolidone) (PVP) was investigated. The resulting Fe(0)-PVP particles were monodispersed and possessed enhancing magnetization saturation. Those synthesis conditions to control the particle size and distribution were exploited.

“…Elemental information can be achieved in combination with atomic or plasma spectrometric techniques. Whereas atomic absorption spectrometry [281][282][283] or ICP-OES 256,284 are rarely used in combination with FFF, as firstly done by Beckett 285 in 1991. Combinations of symmetric flow FFF (Sym4F), 286,287 AF4 [288][289][290][291] and SedFFF 285,292,293 with ICP-MS can be found in the literature.…”

This article reviews the general characterization of nano-objects, especially engineered nanoparticles (ENPs) and discusses analytical techniques commonly used for their determination. The main aspect of this review covers the use of the inductively coupled plasma (ICP) technique for the determination of ENPs itself or when applied in a large variety of products including possible release during use. Beside various applications by direct determination or analysis after suitable digestion also novel approaches e.g. single particle introduction, and hyphenated techniques such as field flow fractionation (FFF) or size exclusion coupled to plasma spectrometry are discussed in detail. Finally, an overview of the stateof-the-art possibilities for quality control related to the atomic spectrometric analysis of nanoparticles is given.

“…17 Kumtabtim et al in 2005 evaluated the size distribution of elements on air particulates using Sd-FFF ICP-OES. 8 Air particulates were collected using a quartz fiber filter and resuspended in solution before fractionation. Various elements (Al, Fe, Mg, and Ti) were monitored on air particulates and their size class evaluated.…”

Field-Flow Fractionation (FFF) is now recognised as a versatile pool of techniques allowing particle size or molar mass to be obtained in a wide variety of samples covering numerous applications in the fields of environment, materials or biology. In the same time, Inductively Coupled Plasma-Mass Spectrometry (ICP-MS) has an indisputable place in the field of elemental detectors and the coupling between FFF and ICP-MS can be considered as an emerging technique capable to reach relevant physico-chemical information at sub-micrometre scale and trace element concentration level. This paper gives some key elements of FFF-based fractionation linking theory and practical analytical aspects, from injection and preconcentration to analysis. The different components of the coupling are described. Summary tables of the main operating conditions of FFF-ICP-MS coupling are presented and operating conditions such as carrier composition, flow and nebulizers are discussed. Special attention is given to the FFF-ICP-MS interface. Qualitative and quantitative analysis is also discussed. Applications in the fields of environment, bioanalysis and nanoparticles are presented in order to illustrate the potentialities of such coupling.
