Silver nanoparticle-assisted preconcentration of selenium and mercury on quartz reflectors for total reflection X-ray fluorescence analysis

An overview of the applications of total reflection X-ray fluorescence spectrometry in food, cosmetics, and pharmaceutical research

“…Microextraction and selective adsorption procedures can also be considered to enhance TXRF microanalytical capability. For instance in the case of Se and Hg determination of low level (0.6 g L −1 ) in seafood samples 110 and in the determination of Sb in milk after nanoparticles immobilization reflectors, 111 respectively.…”

2015 Atomic Spectrometry Update – a review of advances in X-ray fluorescence spectrometry and their applications

“…A report by Romero et al 66 described the trapping of Hg and Se vapours using silver NPs immobilised on quartz reectors prior to their determination by TXRF spectrometry. A report by Romero et al 66 described the trapping of Hg and Se vapours using silver NPs immobilised on quartz reectors prior to their determination by TXRF spectrometry.…”

“…The analysis of nanoparticles (NPs) is of growing interest. A report by Romero et al 66 described the trapping of Hg and Se vapours using silver NPs immobilised on quartz reectors prior to their determination by TXRF spectrometry. The authors described in detail how the quartz reectors were prepared and how the NPs were immobilised on the surface.…”

Silver nanoparticles as a solid sorbent in ultrasound-assisted dispersive micro solid-phase extraction for the atomic absorption spectrometric determination of mercury in water samples

“…[25][26][27][28] Some applications of silver nanoparticles (AgNPs) for the determination of mercury or its removal from contaminated water have been reported. Romero et al 29 used the procedure of trapping Hg vapours using AgNPs immobilized on quartz reectors, prior to their determination by total reection X-ray uorescence. Panichev et al 30 proposed silver and gold nanoparticles impregnated in nylon membrane lters as a new solid phase for preconcentration of mercury from natural waters.…”
