A nanoparticle-based solid-phase extraction procedure followed by flow injection inductively coupled plasma-optical emission spectrometry to determine some heavy metal ions in water samples

Sensitive Detection of Hg2+ with Switchable Electrochemiluminescence Luminophore and Disposable Bipolar Electrode

“…[3] The World Health Organization (WHO) and the US Environmental Protection Agency (EPA) has set the maximum permissible levels of mercury in drinking water at 30 nM [4] and 10 nM, [5] respectively. Traditional techniques for Hg 2 + measurements include atomic emission spectrometry (AES), [6] atomic absorption spectrometry (AAS), [7] atomic fluorescence spectrometry (AFS) [8] and inductively coupled plasma mass spectrometry (ICPMS) [9] . These techniques are reliable and sensitive for Hg 2 + detection.…”

Microextraction Techniques as a Sample Preparation Step for Metal Analysis

“…Main SPE methods for metal ions are summarized in Table 1 (Fritz, 1999). Increasing development of SPE during 1990s continues until recent years by introducing novel solid sorbents such as molecularly imprinted polymers (Lucci et al, 2010) and nanostructured materials (Faraji et al, 2010). SPE has many attractive features in comparison with classical solvent extraction methods.…”

Determination of Palladium Content in Nebivolol HCl Bulk Drug by ICP-OES

“…For the above reasons, ICP-OES has become a tool of choice for estimating metals. Literatures revealed that few methods like determination of metals in food samples like vinegar [9], environmental samples (soil and drinking water) [10][11][12][13][14][15][16], potato chips [17], honey [18] eliphos tablets [19] and escitalopram oxalate bulk drug [20] are reported. This paper describes the methodology and validation procedure by ICP-OES for determination of metals in nebivolol bulk drug and the method was validated according to ICH (Q2R1) guidelines.…”
