Simple mercury determination using an enclosed quartz cell with cold vapour-atomic absorption spectrometry

Abstract

A simple method for determining total inorganic mercury (Hg) in solution using an enclosed quartz cell applying cold vapour-atomic absorption spectrometry (CV-AAS) can reduce sample volume, reductant, and cost compared with those of official methods.

Green-AgNPs modified membrane for monitoring mercury ions in cosmetic sample using pre-concentration assisted voltammetry technique

“…Typically, when assessing mercury levels in cosmetics, the methods commonly employed include Atomic Absorption Spectrophotometry (AAS) [5], Cold Vapor Atomic Absorption Spectrophotometry (CV-AAS) [6], Cold Vapor Atomic Fluorescence Spectrophotometry (CF-AFS) [7], Direct Mercury Analyzer [8] and ICP-MS [9]. These techniques are favored for their superior analytical capabilities, delivering precise results with high accuracy and sensitivity.…”

An Ultrasensitive DNA Sensor for Hg2+ Assay Based on Electrodeposited Au/Carbon Nanofibers‐chitosan and Reduced Graphene Oxide

“…According to the current research, the determination methods of Hg 2 + mainly include atomic absorption/ emission spectrometry [7][8][9], inductively coupled plasma mass spectrometry [10][11][12], atomic fluorescence spectrometry [13][14][15], etc. All of these methods are effective for the detection of Hg 2 + , but they need expensive instruments, complex sample preparation process and complex instrument operation.…”

Paper-Based Analytical Devices for Colorimetric and Luminescent Detection of Mercury in Waters: An Overview

“…For the determination of Hg at the (ultra)trace level, conventional instrumentation is typically used in central labs on a routine basis, such as cold vapor-atomic absorption spectrometry (CV-AAS) [12], cold vapor-atomic fluorescence spectrometry (CV-AFS) [13], electrothermal atomic absorption spectrometry (ETAAS) [14], inductively coupled plasmamass spectrometry (ICP-MS) [15] and total reflection X-ray fluorescence (TXRF) [16]. While these techniques provide adequate sensitivity and precision, they require suitable sampling, preservation procedures, sample pretreatment and a fully controlled laboratory environment, which makes it difficult to extend their application for on-field analysis [17].…”
