Determination of trace mercury species by high performance liquid chromatography–inductively coupled plasma mass spectrometry after cloud point extraction

Recyclable non-ligand dual cloud point extraction method for determination of lead in food samples

“…The CPE method has been widely applied to extract and preconcentrate various metal ions from aqueous solutions (Chen, Chen, Jin, & Wei, 2009;Ghaedi et al, 2009;Mustafa, Erkan, Mehrorang, Mortaza, & Marjan, 2012;Shokrollahi, Ghaedi, Hossainia, Khanjaria, & Soylakb, 2008). Despite the benefits mentioned above, the high viscosity of its surfactant-rich phase will bring trouble to determination.…”

Facile fabrication of an electrochemical aptasensor based on magnetic electrode by using streptavidin modified magnetic beads for sensitive and specific detection of Hg 2+

“…For the detection of Hg 2+ , several methods have been promoted, such as fluorescence spectrometry (Deng et al 2011;Zheng et al 2013), inductively coupled plasma mass spectrometry (ICP-MS) (Chen et al 2009;Long and Kelly 2002), surface-enhanced Raman scattering (SERS) (Duan et al 2012;Yi et al 2013), colorimetry (Chai et al 2010;Lou et al 2011), and ultraviolet-visible spectrometry (Li et al 2014;Zhang et al 2015b). Although these methods can undoubtedly achieve the highly sensitive detection of Hg 2+ , there still existed several problems such as high costs, complex instruments, complicated sample preparation procedures, and time-consuming.…”

Sensitive determination of trace mercury by UV–visible diffuse reflectance spectroscopy after complexation and membrane filtration-enrichment

“…Several analytical techniques have been applied for the determination of mercury, including atomic absorption spectrometry (AAS) [3][4][5], atomic fluorescence spectrometry (AFS) [6][7][8], inductively coupled plasma optical emission spectrometry (ICP-OES) [9], inductively coupled plasma-mass spectrometry (ICP-MS) [10,11], electrochemical method [12] and spectrophotometry [13]. Some sophisticated instrumental techniques are extensively used as standard methods in the determination of mercury but they still possess some disadvantages, such as high cost of instruments, matrix interference and time consuming.…”
