“…63,146 Alternatively, such ionic porous complex composites can form on the surface of Fe 3 O 4 , which serves as a magnetic solid phase extraction (MSPE) adsorbent with enhanced adsorption capacity due to the synergistic effect stemming from multiple contributions by the components in the composites, i.e., inclusion, hydrophobicity, p-complexation, and porosity. 147 In addition to applications in adsorption, a PIL-organic molecule composite can potentially be used as a sensor. Very recently, we have developed a triazolium PIL-TA (trimesic acid) ionic complex membrane bearing two concurrent structure gradients; the two gradients include an electrostatic complexation (EC) degree gradient and a density distribution gradient for a carbene-NH 3 adduct (CNA) along the membrane crosssection (Fig.…”

“…In the reported IL@MPs composites, MPs are synthesized by co-precipitation or solvothermal methods, being Fe 3 O 4 the MPs most commonly used [38,40,41,[43][44][45][46][47][48][49][50][51][52][53][54], but others, such as a mixture of Fe (II) and Co (II) salts [37], have been also reported.…”

Ionic liquids (ILs) are a group of non-conventional salts with melting points below 100 °C. Apart from their negligible vapor pressure at room temperature, high thermal stability, and impressive solvation properties, ILs are characterized by their tunability. Given such nearly infinite combinations of cations and anions, and the easy modification of their structures, ILs with specific properties can be synthesized. These characteristics have attracted attention regarding their use as extraction phases in analytical sample preparation methods, particularly in liquid-phase extraction methods. Given the liquid nature of most common ILs, their incorporation in analytical sample preparation methods using solid sorbents requires the preparation of solid derivatives, such as polymeric ILs, or the combination of ILs with other materials to prepare solid IL-based composites. In this sense, many solid composites based on ILs have been prepared with improved features, including magnetic particles, carbonaceous materials, polymers, silica materials, and metal-organic frameworks, as additional materials forming the composites. This review aims to give an overview on the preparation and applications of IL-based composites in analytical sample preparation in the period 2017–2020, paying attention to the role of the IL material in those composites to understand the effect of the individual components in the sorbent.

“…PAEs can impress on the skin and endocrine system, cause carcinogenicity and also influence the genital development. [4][5][6] The scientific researchers have also proved that PAEs at high concentrations may hurt human organs like lung, kidney and liver. 7 According to European Food Safety Authority (EFSA) tolerable daily intake (TDI) values for DEHP, DnBP, BBP and DBP are 0.05, 0.01, 0.15 and 0.04 mg kg -1 , respectively.…”
