Simple approaches to on-line and off-line speciation analysis of mercury in flue gases with detection by atomic absorption spectrometry: A pilot study

Ultratrace determination of arsenic by hydride generation atomic absorption spectrometry with preconcentration on gold nanoparticles

“…Two of them were solid: gold wire (specied in Section 2.1) and powdered gold coated alumina (amalgamator lling) used commercially to preconcentrate mercury cold vapors in Hg analyzers. 26,27 The last material tested was the solution of gold nanoparticles (AuNPs) (see Section 2.1 for details). For the sake of simplicity, empty amalgamator tubes were used as traps also with the other two gold based preconcentration materials tested.…”

“…The amalgamator lling was a gold-coated alumina, a mean Al 2 O 3 grain size of 150 mm as separated by sieve analysis. 26 The gold content was determined to be 10% Au (m m À1 ). 26 2.4.2 Gold wire.…”

Greenish‐Yellow Emitting Carbon Dots as ‘On‐Off‐On’ Fluorescent Probe for Selective Determination of Mercury (II) and Sulphide Ions

“…Hence, it is necessary to develop simple operative system to detect sulphide ions from biological and environmental concern. [8][9][10][11] To date, number of conventional methods, such as atomic absorption spectroscopy (AAS), [12] inductively coupled plasma mass spectrometry (ICP-MS), [13] atomic fluorescence spectroscopy (AFS) [14] and atomic emission spectroscopy (AES) [15] have been used for mercury detection.However, the routine use of these techniques is restricted due to limitations associated with these techniques such as lengthy and complicated sample preparation procedures and sophisticated instrumentation. On the other hand, carbon dots as a fluorescent sensor shows high sensitivity, involves effortless procedure and provide rapid results.…”

Sequential injection analysis for mercury ion with modified screen – printed carbon electrode

“…To date, monitoring trace amount of mercury is very important. Various techniques have been exploited including atomic absorption spectrometry [20][21][22], atomic fluorescence spectrophotometry [23], quartz crystal microbalance [24], inductively coupled plasma mass spectrometry [25][26][27], surface-enhanced Raman scattering [28] and X-ray spectrometry [29,30]. However, these techniques suffer from time-consuming, well-trained operators, large sample requirement, expensive costs, and not suitable for a sample pre-treatment or for in situ analysis.…”
