In-atomizer atom trapping on gold nanoparticles for sensitive determination of mercury by flow injection cold vapor generation atomic absorption spectrometry

Synthesis of double gold nanoclusters/graphene oxide and its application as a new fluorescence probe for Hg2+ detection with greatly enhanced sensitivity and rapidity

“…There is a very good agreement between the results obtained by proposed method and cold vapor generation atomic absorption spectrometry (CVGAAS). 26 These indicated proposed method has a good accuracy and precision.…”

Integrating photochemical vapor generation with photo-oxidation trapping for effective mercury removal from polluted water and its on-line monitoring

“…Therefore, it is necessary to develop techniques to on-line trap the generated mercury vapor after separation from the treated water. In previous works [29,30], mercury vapor (Hg 0 ) could be efficiently trapped on the surface of various materials by forming HgO or amalgams. To the best of our knowledge, this is the first report using photo-oxidation for direct trapping mercury on the surface of a quartz transport tube.…”

Atomic spectrometry update: review of advances in the analysis of clinical and biological materials, foods and beverages

“…The procedure had an LOD of 0.01 mg L À1 and accuracy was demonstrated using a number of CRMs and comparison against results by ICP-MS. A novel development by Peng et al 79 utilised gold nanoparticles to coat the surface of a quartz tube atomiser for Hg determination with AAS. Ajtony et al 77 developed a method for the measurement of As, Cd, Cr, Cu, Pb, and Se in various water samples (snow, tap and well).…”

“…Peng et al 79 described a novel method for the determination of total Hg in biological matrices using atomtrapping CV-AAS. Whilst attention has again primarily focused on methods for sample preparation and on the speciation of Hg in biological matrices (described in Sections 3.2 and 5.1), other groups continue to describe methods for the determination of total Hg.…”
