“…In response to the external environment, the structures and properties of stimuli‐responsive ILs are changed and lead to the regulation of aggregation structure and phase behavior, which lay the foundation for the use of such ILs. Due to their special on‐off properties and unique controllable and reversible characteristics, the stimuli‐responsive ILs successfully meet the needs of homogeneous reaction, heterogeneous separation, ILs recovery, and system circulation in applications, such as catalysis, extraction, separation, [ 93‐94,108,112,144‐146 ] 3D netlike porous films, [ 46 ] CO 2 absorption, [ 149 ] etc . Moreover, the use of simulation methods such as CO 2 , magnetism, temperature, and light is more attractive in practical applications as additional substances can be avoided.…”

“…2) Stimuli‐responsive ILs are also crucial in extraction and separation due to the advantages of low pollution, short separation time, simple operation, reused extractant, and high extraction efficiency. The main methods reported for stimuli‐responsive ILs in extraction and separation are magnetic [ 144‐145 ] and temperature ones, [ 93‐94,108,112,146 ] and the former mainly uses dispersive liquid‐liquid microextraction (DLLME) method, while the latter adopts the homogenous liquid−liquid extraction (HLLE) method. As shown in Figure 25, the magnetic response characteristic of [N 1,8,8,8 ][FeCl 4 ] was used to collect and separate MIL phases rich in analytes quickly, and then was determined by HPLC‐UV method.…”

“…Under optimal conditions, the relative recovery rates of methyl hydroxybenzoate, ethyl hydroxybenzoate, and propyl hydroxybenzoate extracted from tap water, wastewater, beer, and peach juice were in the range of 95%—103 %. [ 144 ] The HLLE method was used to extract Au(III) from the acid chloride medium with UCST‐type IL [EtbetmMor][Tf 2 N] of high extraction efficiency at 97.8%. Also, [EtbetmMor][Tf 2 N]‐water system was used to recover gold from a variety of metal solutions with high recovery and selectivity for Au(III).…”

Ionic liquids with stimuli‐responsive characteristics are an essential branch in the comprehensive ionic liquids' family, which can meet the controllable and reversible needs in practical applications with different stimulation means. In this review, we summarize the recent research progress of these stimuli‐responsive ionic liquids, mainly focusing on their chemical structures, properties, responsive mechanism, aggregation structures, and phase behaviors, which were driven by external stimuli, such as CO2, magnetism, light, temperature, redox, and pH. Then, the particular or potential applications of stimuli‐responsive ionic liquids are expounded in various fields of science, including catalytic reaction, extraction, separation, nanomaterial preparation, and gas absorption. In the end, the challenges and strategies of the subject are briefly presented. It is expected that this review will contribute to the rational design and applications of stimuli‐responsive ionic liquids in the future.

“…Regarding the ultrasonic time, as indicated in Figure 2d, the maximum peak area was obtained at a decreased sonication time and an increased rotation speed probably due to the partial solubility of the IL at a prolonged sonication time [37]. Besides, it seems that centrifuge speed eradicates the cloudy solution and has effects on the volume of the extraction solvent [38].…”

trans,trans‐Muconic acid has been widely used as a biomarker in biological monitoring of benzene‐exposed workers during routine occupational health services. In the present study, a novel microextraction technique, in‐syringe ionic liquid‐dispersive liquid–liquid microextraction, was implemented for preconcentration of trans,trans‐muconic acid followed by analytical determination by high‐performance liquid chromatography with ultraviolet detection. Moreover, the important variables affecting the performance of applied microextraction technique including needle diameter, volume of the spiked sample, volume of the ionic liquid, salt addition, rotation speed of centrifugation, centrifuge time, and ultrasonic time were optimized by experimental design. A good linear relationship was observed at the range of 0.032–10 μg/mL between the peak area and the concentration levels (R2 = 0.9997). The limit of detection and extraction recovery for trans,trans‐muconic acid were 0.011 μg/mL and >96.2%, respectively. This method provided easy and rapid analysis of low amounts of trans,trans‐muconic acid in human urine with simple equipment.

Magnetic Ionic Liquids in Sample Preparation: Recent Advances and Future Trends

In the last decades, a myriad of materials has been synthesized and utilized for the development of sample preparation procedures. The use of their magnetic analogues has gained significant attention and many procedures have been developed using magnetic materials. In this context, the benefits of a new class of magnetic ionic liquids (MILs), as non-conventional solvents, have been reaped in sample preparation procedures. MILs combine the advantageous properties of ionic liquids along with the magnetic properties, creating an unsurpassed combination. Owing to their unique nature and inherent benefits, the number of published reports on sample preparation with MILs is increasing. This fact, along with the many different types of extraction procedures that are developed, suggests that this is a promising field of research. Advances in the field are achieved both by developing new MILs with better properties (showing either stronger response to external magnetic fields or tunable extractive properties) and by developing and/or combining methods, resulting in advanced ones. In this advancing field of research, a good understanding of the existing literature is needed. This review aims to provide a literature update on the current trends of MILs in different modes of sample preparation, along with the current limitations and the prospects of the field. The use of MILs in dispersive liquid–liquid microextraction, single drop microextraction, matrix solid-phase dispersion, etc., is discussed herein among others.
