Hollow fiber supported ionic liquid membrane microextraction for speciation of mercury by high-performance liquid chromatography-inductively coupled plasma mass spectrometry

Abstract

Hollow fiber supported ionic liquid membrane microextraction for the preconcentration of monomethylmercury and inorganic mercury with high sensitivity detection.

A Bibliometric Analysis of Research on Supported Ionic Liquid Membranes during the 1995–2015 Period: Study of the Main Applications and Trending Topics

“…The investigation of the relative parameters that affect extraction efficiency and selectivity (such as type of ionic liquid membrane, presence of a carrier, extraction time, pH of the donor sample and acceptor phase, stirring conditions during extraction, or sample salinity) is the main objective of the researchers in this topic, in order to optimize the conditions and propose the most convenient analytical methods. Simple hollow fibre supported liquid phase microextraction (HF–LPME) with ILs can also be applied to the determination of metal concentrations in environmental samples, with examples of their employment for hexavalent chromium [ 151 ] and mercury [ 152 ], which use polypropylene supports with Aliquat 336 and [BMIM][PF 6 ] with 0.02% dithizone as ILs, respectively.…”

Temperature-controlled ionic liquid dispersive liquid–liquid microextraction combined with fluorescence detection of ultra-trace Hg2+ in water

“…4 As a result, accurate and highly sensitive sensors of trace Hg 2+ are in high demand. Various methods have been reported for the detection of Hg 2+ in the ng L À1 range, among which atomic absorption spectrometry (AAS), 5,6 atomic uorescence spectrometry (AFS), [7][8][9] and inductively coupled plasma mass spectrometry (ICP-MS) 10,11 are popular methods. However, these methods require very expensive, complex and bulky instrumentation.…”

Solvent bar micro-extraction with graphite atomic absorption spectrometry for the determination of silver in ocean water

“…Recent use of room temperature ionic liquids (RTILs), which are organic salts that are liquid at working temperature, as additives for the organic solution in 3HFLPME has supposed a breakthrough for the stability of the organic solution in the fiber pores [23][24][25]. RTILs have been used to enhance pre-concentration of several metals as Au, Cd, Cr, Ni, or Pb [24,[26][27][28].…”
