“…Only one symmetry direction is apparent for PAN with 70 vol% dodecanol. This change might be attributed to the higher dodecanol viscosity hindering imaging, however, this is at odds with the clear images seen in pure PAN, which has a much higher viscosity 48 than either dodecanol 49 or PAN + dodecanol mixtures. 50 Dodecanol might also be solvophobically adsorbed to the solution-facing propyl chains of the adsorbed cations, which would hinder imaging; solvophobic attractions would be strongest for dodecanol due to its long alkyl chain, and decrease in strength as alkyl chain length is decreased.…”

PAN is a protic ionic liquid (IL) which has a bicontinuous sponge-like nanostructure of polar and apolar domains in the bulk, which becomes flatter near a solid surface. Mixtures of PAN with 1-butanol, 1-octanol, and 1-dodecanol at 10 -70 vol% n-alkanol have been examined, along with each pure n-alkanol, to reveal the effect of composition and n-alkanol chain length. At low concentrations the butanol simply swells the PAN nearsurface nanostructure, but at higher concentrations the nanostructure fragments. Octanol and dodecanol first lower the preferred curvature of the PAN near-surface nanostructure because, unlike n-butanol, their alkyl chains are too long to be accommodated alongside the PAN cations. At higher concentrations, octanol and dodecanol self-assemble into n-alkanol rich aggregates in a PAN rich matrix. The concentration at which aggregation first becomes apparent decreases with n-alkanol chain length.2

“…The variations of the excess properties with the molecular size of 1-alkanols and temperature were investigated. Although the physical properties data of the pure components (phenetole and 1-alkanols) are available in the literature [8][9][10][11][12][13][14][15][16][17][18][19][20][21], but no experimental data are available for these mixtures at the comparable conditions of this study.

“…All results regarding the influence of organic additives on the three TSILs used are shown in Table S1 ; for [P 66614 ][HNA] and dodecan-1-ol the results are additionally depicted in Figure 1 a. In the case of [P 66614 ][HNA], the viscosity of the pure TSIL was previously determined as 719 cP [ 30 ], which is reduced by adding less viscous dodecan-1-ol (16.1 cP [ 31 ]). Nevertheless, no clear negative correlation between extraction efficacy and concentration of organic additive was evident.…”

Solvent Bar Micro-Extraction of Heavy Metals from Natural Water Samples Using 3-Hydroxy-2-Naphthoate-Based Ionic Liquids

Developments in the liquid micro-extraction of trace metals from aqueous phases have proven to be limited when extended from pure water to more complex and demanding matrices such as sea water or wastewater treatment effluents. To establish a system that works under such matrices, we successfully tested three task-specific ionic liquids, namely trihexyltetradecyl- phosphonium-, methyltrioctylphosphonium- and methyltrioctylammonium 3-hydroxy-2-naphthoate in two-phase solvent bar micro-extraction (SBME) experiments. We describe the influence of pH, organic additives, time, stirring rate and volume of ionic liquid for multi-elemental micro-extraction of Cu, Ag, Cd and Pb from various synthetic and natural aqueous feed solutions. Highest extraction for all metals was achieved at pH 8.0. Minimal leaching of the ionic liquids into the aqueous phase was demonstrated, with values < 30 mg L−1 DOC in all cases. Sample salinities of up to 60 g L−1 NaCl had a positive effect on the extraction of Cd, possibly due to an efficient extraction mechanism of the present chlorido complexes. In metal-spiked natural feed solutions, the selected SBME setups showed unchanged stability under all conditions tested. We could efficiently (≥85%) extract Cu and Ag from drinking water and achieved high efficacies for Ag and Cd from natural sea water and hypersaline water, respectively. The method presented here proves to be a useful tool for an efficient SBME of heavy metals from natural waters without the need to pretreat or modify the sample.
