This perspective addresses the replacement of harmful organic solvents by a novel generation promising alternatives using sustainable analytical methodologies.

The reliability of thermodynamic modeling, particularly for ionic liquid (IL) and solute systems, can be critically compromised by conflicting activity coefficient data within databases such as ILThermo. These discrepancies, often arising from variations in experimental conditions or inconsistencies the source, lead to skewed predictions hinder accurate analysis. This issue directly impacts design optimization processes involving liquids (ILs), separation, extraction, catalysis, where...

A new sorption system for isolation/enrichment of polar organic analytes from aqueous samples was obtained by substantial modification the solid-phase microextraction (SPME) probe. In this system, sorbents are separated sample a hydrophobic membrane. The membrane SPME (M-SPME) probe made utilizing polyethylene glycol (PEG) (molecular weight = 20 kDa) and polydimethylsiloxane (PDMS) as material. probe, PEG behaves pseudo-liquid at extraction stage, whereas, up to now, it has mainly been used...

High loadings of the IL 1-methyl-3-butylimidazolium bis(trifluoromethylsulfonyl)imide ([C4MIM][TFSI]) confined within network. Coatings composition morphology using scanning electron microscopy energy dispersive X-ray spectrometry. The obtained ionogel SPME fibers exhibited high extractability for aromatic...

Sample preparation has been one of the most often investigated steps in analytical procedures. These investigations are focused on problems such as isolation analytes from sample matrix, matrix simplification, analyte enrichment to level above detection limit instrumentation used, and removal interfering species improve final determination. Techniques based solid (adsorption) pseudo liquid (absorption) media play an important role because their universal applicability, possibility automation...

Densities of some acetonitrile solutions ionic liquids based on N-alkyl-N-methyl-morpholinium cations, N-ethyl-N-methylmorpholinium bis(trifluoromethanesulfonyl)imide, N-butyl-N-methylmorpholinium N-methyl-N-octylmorpholinium bis(trifluoromethanesulfonyl)imide and N-decyl-N-methylmorpholinium were measured at T = (298.15–318.15) K atmospheric pressure.

Ionic liquids (ILs) provide a promising solution in many industrial applications, such as solvents, absorbents, electrolytes, catalysts, lubricants, and others. However, due to the enormous variety of their structures, uncovering or designing those with optimal attributes requires expensive exhaustive simulations experiments. For these reasons, searching for an efficient theoretical tool finding relationship between IL structure properties has been subject research studies. Recently, special...

Preparation of samples for analysis, first all isolation and/or enrichment analytes, is becoming a key stage each analytical procedure including determination trace components. Effectiveness this stage, i.e., analyte enrichment, removal interferents and change the original sample matrix, depends both on chosen extraction technique utilized materials reagents. Though liquid-liquid still widely used in practice, it seems that solid phase (SPE) techniques are gaining dominating position. In...

Ionogels, a family of hybrid materials in which ionic liquids (ILs) are confined sol-gel network, receiving much attention variety scientific and technological fields. In this work, ionogels derived from three different ILs based on the anion bis(trifluoromethanesulfonyl)imide (TFSI), namely 1-butyl-3-methylpyridinium ([C4C1Py][TFSI]), 1-butyl-1-methylpyrrolidinium ([C4C1Pyrr][TFSI]), 1-butyl-1-methylpiperidinium ([C4C1Pip][TFSI]) were obtained outer surface optical fibres by technology.
