A comparison of different nanoscopic silver species with respect to their capacity to bind mercury from the gas-phase using total reflection X-ray fluorescence

X-ray fluorescence spectrometry for environmental analysis: Basic principles, instrumentation, applications and recent trends

“…In a recent publication, acrylic glass discs and silicon waters were shown to be suitable carriers, with sufficiently smooth and clean surfaces, for TXRF analysis of PM as well (Seeger et al, 2021). Finally, in addition to PM characterization, TXRF has also been used to determine the concentration of airborne Hg (Böttger et al, 2020). In this case, Hg was trap onto quartz reflectors coated with Ag nanoparticles and further analysed by TXRF.…”

Atomic spectrometry update – a review of advances in X-ray fluorescence spectrometry and its special applications

“…As TXRF spectrometry is a micro analytical tool, it would be well suited for the determination of heavy metals at such low concentrations if issues of sample collection and calibration could be overcome. Böttger et al 49 used silver NP to study the efficiency of Hg collection from ambient air. The LOD for 24 h sampling and 500 s measurement time was 18 ng m −3 when 10 nm silver NP stabilised with citrate and BH 4 − were used.…”

UV‐Induced Oxidation Preparation of Multi‐Functional Lignin‐Based AgNPs and its Application for Conductive Coating, Antibacterial Enhancement, and Product Separation

“…As a polyphenolic anionic surfactant, lignin has the potential to regulate the photo‐oxidation behavior of AgNPs due to its redox activity and the chelation characteristics between anionic groups and Ag + [25,26] . Meanwhile, it was reported that lignin‐coated AgNPs were not chemically inert and could be oxidated by mercury ions [12,27] …”

“…[25,26] Meanwhile, it was reported that lignin-coated AgNPs were not chemically inert and could be oxidated by mercury ions. [12,27] Inspired by oxidative depolymerization of lignin under UV irradiation in THF medium, [28] the system of UV-induced THF autoxidation was used for oxidative degradation of the lignin coating and etching AgNPs to achieve the preparation of multifunctional products. The UV-induced oxidation behavior of lignin-based AgNPs was studied systematically.…”
