“…Although the negligible volatility of ILs is one appealing point in the use of ILs in place of volatile organic solvents, the finite solubility of ILs in water has raised concern in wastewater treatments and other circumstances. [169][170][171][172][173][174][175][176][177][178][179][180][181][182][183][184][185][186][187] Since ILs are salts having certain solubility in water, the interface between an IL and water is inevitably electrified. There are a number of systems in which the phase-boundary potential across the IL|W interface plays a crucial role in determining the physicochemical characteristics of the systems.…”

Liquid-liquid two-phase systems formed by a hydrophobic ionic liquid and water find several useful ways of application in analytical chemistry. One of the most important properties of such two-phase systems is the mutual solubility of the IL and water. Recent advancements on this subject have been reviewed. The solubility of ionic liquids in water is related to the standard Gibbs energies of the transfer of ions constituting the ionic liquid from the ionic liquid phase to water. Although this single ionic property cannot be measured thermodynamically and also varies from one ionic liquid to another, the standard Gibbs energy of the ion transfer from a polar aprotic solvent, such as nitrobenzene and 1,2-dichloroethane, to water is a convenient measure for it. The solubility of an ionic liquid in water and the electrochemical properties at the interface between the two phases are intimately related with each other.

“…With reference to this problem, along with scientific reports on the synthesis, physical and chemical properties and the potential for practical utilization of ionic liquids, a large number of studies have come up, which are concerned with the examination of the potential toxicity of these substances. Studies described in available literature reveal varied influences of ionic liquids on microorganisms [1,2,[17][18][19][20][21][22], plankton [21,[23][24][25][26], invertebrates [27][28][29], vertebrates [27,30], algae [2,21,23,29,[31][32][33], fungi [19,34,35] or higher land plants [8,21,31,[36][37][38][39]. The quoted literature shows that a likely toxic influence of a ionic liquid is determined by a number of factors, of which the primary role is played the cation type and the length of the substituent in the cation (as a rule, the longer alkyl chain, the higher toxicity).…”

Ionic liquids have attracted considerable interest in various areas as new, non-volatile and nonflammable organic solvents, catalysts, reaction additives, ligands, drugs and other dedicated materials etc. Their general use, sometimes in bulky quantities, requires determination of their potential ecotoxicity on selected organisms. In the present work, influence of triphenylmethylphosphonium iodide (1) and triphenylhexadecylphosphonium iodide (2), introduced to soil, on germination and early stages of growth and development of superior plants was investigated using the plant growth test based on the OECD/OCDE 208/2006. In this test, the seeds of selected species, i.e. land superior plants -spring barley (Hordeum vulgare) and common radish (Raphanus sativus L. subvar. radicula Pers.) were planted in pots containing soil to which a test chemical compound had been added and in pots with control soil. To evaluate the phytotoxicity of ionic liquids 1 and 2 germination and weight (dry and fresh) of control plant seedlings were determined and compared with the germination and weight (dry and fresh) of the seedlings of plants grown in the soil watered with appropriate amounts of the test chemicals. The visual assessment of any types of damage to the test species, such as growth inhibition, chlorosis and necrosis, was also carried out and documented by digital photographs. Based on the obtained results, magnitudes of the LOEC -the lowest concentration causing observable effects in the form of reduction in growth and germination compared with the control and the NOEC -the highest concentration not causing observable, toxic effects -were also determined.

“…Over the past two decades, Ionic liquids (ILs) have attracted considerable attention as friendly environmental substitutes for volatile organic solvents due to the several unique properties such as negligible vapor pressure, high thermal stability, easy recyclability, no flammability, and high ionic conductivity [1][2][3][4]. Generally, ILs are a group of low-melting-point salts containing organic cation, such as imidazolium, pyrrolidinium, or pyridazinium, paired with various anions, such as bromide or tetrafluoroborate [5].…”
