Abstract:A solid-phase dispersive microextraction procedure has been developed using ferrite (Fe3O4), an inexpensive magnetic material, as an adsorbent for the separation and subsequent determination of Ga(III) and In(III). The ions were removed from an aqueous solution by adsorption on Fe3O4, which was next easily collected from the medium by the action of a magnet. The analytes were then desorbed using 50 µL of 2 M NaOH or 50 µL of a 4:1 mixture of 0.1 M EDTA and 2 M HNO3 for the determination of Ga(III) or In(III), … Show more
“…For example, atomic absorption spectroscopy (AAS) is employed for total mercury and methylmercury analysis in dried blood and fish samples. [17][18][19][20] Cold vapor atomic fluorescence spectrometry (CV-AFS) is employed for detecting mercury in environmental water samples. [21][22][23] Additional methods include cold vapor atomic absorption spectroscopy (CV-AAS), 24 inductively coupled plasma-mass spectrometry (ICP-MS), [25][26][27] anodic stripping voltammetry, 28,29 and X-ray fluorescence spectrometry (XFS).…”
Mercury (Hg) contamination remains a major environmental concern, primarily due to its presence at trace levels, making monitoring its concentrations challenging. Sensitivity and selectivity are significant challenges in the development...

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
