Preconcentration and determination of trace Hg(ii) using ultrasound-assisted dispersive solid phase microextraction

Abstract

Hg(ii) ion adsorption onto an MoS2 surface.

Preparation and performance study of rhodamine B naphthylamide, a fluorescent probe, for the detection of Fe3+

“…Although these methods have high sensitivity, they are complicated to operate and require sophisticated detection instruments, making their widespread use difficult to achieve. [12][13][14][15][16][17] With the development of technology, uorescence chromatography using uorescent probes for metal detection has attracted great attention because of its cost-effectiveness and excellent detection performance. 18,19 There have been many reports on the detection of Fe 3+ using uorescent probe methods.…”

Determination of Hg(II) and Methylmercury by Electrothermal Atomic Absorption Spectrometry after Dispersive Solid-Phase Microextraction with a Graphene Oxide Magnetic Material

“…In recent years, different microextraction techniques coupled with atomic absorption spectrometry have been used for the determination of Hg(II) [15][16][17]; however, very few works are found in the literature in which the speciation of mercury and its subsequent quantification are carried out [18]. Moreover, the analysis of MeHg in water samples is usually carried out using chromatographic techniques, although a derivatizing treatment of the sample is required [19,20].…”
