Characterization of solid magnetic nanoparticles by high resolution continuum source electrothermal atomic absorption spectrometry (HR-CS-ETAAS)
(2015-12-21)Nanometer-sized materials have attracted substantial interest in the scientific community because they offer a highly active surface area to volume ratio enable them to have a wide range of potential applications because ... -
Development of a new method for preconcentration, chemical vapour generation and determination of metal ions by ICP OES in environmental samples using magnetic nanoparticles
(2015-12-21)Silica-coated magnetic nanoparticles (MNP SCMNPs) modified with [1,5-bis (2-pyridyl)-3-sulphophenyl methylene] thiocarbonohydrazide were synthesized by a sol-gel method. These magnetic nanoparticles (PSTHmnp) were employed ... -
Extraction, preconcentration and determination of arsenic in drinking water by HR GFAAS.
(2024)Heavy metals, such as arsenic, are major environmental pollutants with significant adverse effects on human health and the ecosystem. Arsenic, in its various chemical forms, is widely distributed due to industrial and ... -
Optimization of the synthesis of functionalized magnetic nanoparticles and their characterization
(2015-12-21)Magnetic nanoparticles (MNPs), a new kind of nanometer-sized material, are widely used in the fields of biotechnology and biomedicine. These particles are superparamagnetic, which means that they are attracted to a magnetic ... -
Optimization of the synthesis of magnetic nanoparticles by solid sampling high resolution continuum source graphite furnace atomic absorption spectrometry and multi-response surface methodology
(2016-10-04)Magnetic nanoparticles (MNPs) are a new kind of nanometer-sized materials superparamagnetic with potential applications as magnetic carries for various biomedical uses, wastewater remediation, preconcentration of various ... -
Synthesis and characterization of a new nanosorbent based on functionalized magnetic nanoparticles and its use in the determination of mercury by FI-CV-ETAAS
(2015-07-20)In this work, a new chelating sorbent which employs 1,5-bis(di-2-pyridil)methylene thiocarbohydrazide as the functional group and magnetic nanoparticles (MNPs) as its support (DPTH-MNP) was synthetized and characterized. ...
