Magnetomotive room temperature dicationic ionic liquid: A new concept toward centrifuge-less dispersive liquid–liquid microextraction

Liquid-phase microextraction combined with graphite furnace atomic absorption spectrometry: A review

“…Special attention has been paid to high-resolution continuum-source graphite furnace atomic absorption spectrometry (HR-CS-GFAAS). [56] has been reported. In most of cases, the extract is diluted in a ratio 1:1 to 1:6.…”

“…Second, a technique named as homogeneous liquid-liquid microextraction via flotation assistance (HLLME-FA) makes use of N 2 flotation to transfer the dispersed solvent to the surface so that phase separation takes place [55]. Third, a technique named as magnetic room temperature dicationic ionic M A N U S C R I P T A C C E P T E D ACCEPTED MANUSCRIPT 13 liquid-dispersive liquid-liquid microextraction (MRTDIL-DLLME) has been recently reported by Beiraghi et al [56]. This technique is based on the use of magnetic ILs as extractant phases.…”

“…Aqua regia has been used for digesting ore and Pt alloy samples prior to Au and Ag determination [56,60,158]. [116].…”

“…Finally, the entire program is run after deposition of the sample [6,18,112]. Pd is the most common chemical modifier used for determining Ag [56,74] Usually, the use of complexing agents increases the stability of the analyte in the graphite furnace. However, volatilization of some elements could occur due to particular complexing agents.…”

Versatile ligands for high-performance liquid chromatography: An overview of ionic liquid-functionalized stationary phases

“…In recent years, an avalanche of successful applications has been emphatically summarized in many review articles [12][13][14][15][16][17][18]. In separation science, ILs play a very important role in extraction, either as a biphasic solvent for dispersive liquid-liquid microextraction [19][20][21][22][23][24] or immobilized ligands on supports for SPE and SPME [12,[25][26][27], due to their convenient tunability to realize selective extraction and high preconcentration of target molecules; taking advantage of their high thermal stability and multiple interactions, ILs have also been used as stationary phases (SPs) for gas chromatography (GC) [28][29][30][31]; capillary electrochromatography (CEC) and capillary electrophoresis (CE) have as well benefitted immensely from the usage of ILs in modifying capillary [32][33][34][35][36]. In high-performance liquid chromatography (HPLC), ILs, imidazolium salt in most cases, are exceptionally useful.…”
