Minimization of mass interferences in quadrupole inductively coupled plasma mass spectrometric (ICP-MS) determination of palladium using a flow injection on-line displacement solid-phase extraction protocol

Atomic spectrometry in China: past and present

“…66 In fact, the competition between target ions and other co-existing metal ions to interact with the complexing agent or active sites on the inner walls of the KR remains a problem in metal-chelate based preconcentration systems. Yan et al thus proposed a highly selective quantication method based on the displacement-sorption protocol for FAAS, 187 ETAAS 188 and ICPMS, 189 in which interferences from co-existing metal ions were largely minimized.…”

Self-assembly pipette tip-based cigarette filters for micro-solid phase extraction of ketoconazole cis-enantiomers in urine samples followed by high-performance liquid chromatography/diode array detection

“…CFs have been successfully used as an alternative sorbent material for pre-concentration and extraction of organic [18][19][20][21][22][23][24] and inorganic compounds. [25][26][27][28][29][30][31][32][33][34] To date, studies have been conducted to extract organic analytes only from water using high-performance liquid chromatography and gas chromatography-mass spectrometry. Inorganic analytes were extracted from sh, food and seafood, road dusts, road side soils, rock, water and biological samples using CFs as an adsorbent coupled to ame atomic absorption spectrometry, electrothermal atomic absorption spectrometry, ow injection and atomic uorescence spectrometry systems.…”

Flame Atomic Absorption Spectrometric Determination of Palladium in Aqueous Samples after Preconcentration Using Nanoparticles of γ-Alumina Functionalized with Pyridine Groups

“…5,6 So far, several methods for preconcentration and separation of trace amount of metals from various samples have been developed and used according to nature of the sample. 7 Liquid-liquid microextraction, 8 liquid-liquid extraction, 9,10 membrane disk extraction, 11 coprecipitation, 12,13 cloud point extraction, 14,15 leaching, 16 cyanidation, 17,18 adsorption process 19 and solid phase extraction (SPE) [20][21][22][23] are the most popular methods for this aim. Among these techniques, SPE is one of the most important preconcentration methods because of its simplicity, flexibility of choice of the solid phase, high preconcentration factor, low consumption of the organic solvents, low cost and extraction time for sample preparation.…”
