Selective Determination of Mercury(II) Ion in Water by Solvent Extraction Followed by Reversed‐Phase HPLC

Glutathione-protected silver nanoclusters for sensing trace-level Hg2+ in a wide pH range

“…[12][13][14] The development of sensors for Hg 2+ (one of the most stable inorganic forms of mercury) is in high demand because mercury is a hazardous and toxic substance that can damage the brain, heart, kidney, stomach, and intestines, even at very low concentrations. 15,16 A number of methods to detect trace concentrations of Hg 2+ in different samples have been explored, such as circular dichroism, 17 high performance liquid chromatography (HPLC), 18,19 inductively coupled plasma mass spectrometry (ICP-MS), 20,21 electrochemical methods, atomic absorption/emission spectrometry (AAS/AES), [22][23][24][25][26] atomic uorescence spectrometry (AFS), 27,28 ame photometry (FP) and ion selective electrodes (ISE). 29 However, all of these procedures have limitations that include the need for sophisticated instrumentation and technical expertise, as well as long analysis times.…”

A simple visual and highly selective colorimetric detection of Hg2+ based on gold nanoparticles modified by 8-hydroxyquinolines and oxalates

“…Traditional detection methods for Hg 2+ include atomic absorption spectrometry, 4 inductively coupled plasma mass spectroscopy 5 and inductively coupled plasma-atomic emission spectrometry, 6 atomic fluorescence spectrometry, 7 high-performance liquid chromatography, 8 ion selective electrodes and flame photometry. 9,10 However these methods need costly instruments or complex procedures, which are inconvenient and time-consuming.…”

Functionalized Silver Nano-Sensor for Colorimetric Detection of Hg2+ Ions: Facile Synthesis and Docking Studies

“…Consequently, the environmental concern about regulating this contaminant demands the development of new mercury detection methods that are cost-effective, rapid and facile in nature [ 8 ]. Certain conventional techniques such as atomic absorption spectroscopy (AAS) [ 9 ], inductive coupled plasma mass spectrometry (ICPMS) [ 10 ], high performance liquid chromatography (HPLC) [ 11 ], ion selective electrode (ISE) and flame photometry [ 12 ] are currently used for the determination of Hg 2+ . Electrochemical analysis is demonstrated as an excellent tool in terms of device operation, cost of instrumentation and instantaneous application.…”
