Sample pretreatment is essential for the analysis of complicated real samples due to their complex matrices and low analyte concentrations. Among all sample pretreatment methods, solid‐phase extraction is arguably the most frequently used one. However, the majority of available solid‐phase extraction adsorbents suffer from limited selectivity. Molecularly imprinted polymers are a type of tailor‐made artificial antibodies and receptors with specific recognition sites for target molecules. Using molecularly imprinted polymers instead of conventional adsorbents can greatly improve the selectivity of solid‐phase extraction, and therefore molecularly imprinted polymer‐based solid‐phase extraction has been widely applied to separation, clean up and/or preconcentration of target analytes in various kinds of real samples. In this article, after a brief introduction, the recent developments and applications of molecularly imprinted polymer‐based solid‐phase extraction for determination of different analytes in complicated real samples during the 2015‐2020 are reviewed systematically, including the solid‐phase extraction modes, molecularly imprinted adsorbent types and their preparations, and the practical applications of solid‐phase extraction to various real samples (environmental, food, biological, and pharmaceutical samples). Finally, the challenges and opportunities of using molecularly imprinted polymer‐based solid‐phase extraction for real sample analysis are discussed.

“…Different analytical instruments such as inductively coupled plasma atomic emission spectrometry (ICP-AES) [3,4], electrothermal atomic absorption spectroscopy (ETAAS) [5][6][7][8], and inductively coupled plasma mass spectrometry (ICP-MS) [9,10] have been reported for determination of metal ions. ICP-AES has limits of detection (LODs) in the ppt (ng L -1 ) to ppb (μg L -1 ) range.…”

“…Various sample pretreatment methods such as cloud point extraction (CPE) [4], co-precipitation [11], liquidliquid extraction (LLE) [6], and solid-phase extraction (SPE) [7,12] have been used to preconcentrate metal ions and eliminate matrix effects. Some advantages of the SPE technique such as the short extraction time, low consumption of organic solvents, and adsorbents have resulted in the wide applications of this method for extraction of various organic and inorganic pollutants [13].…”

A simple and sensitive method was developed for preconcentration of the several transition metal ions using Santa Barbara Amorphous‐15 mesoporous silica functionalized with the ethylenediaminetetraacetate functional group. The determination of the metal ions was performed by inductively coupled plasma atomic emission spectrometry. The effective parameters on the extraction efficiency of the ions were investigated. The optimized conditions were: the sample solution pH 4, adsorbent amount = 10 mg, adsorption time = 30 min, elution solvent = 1.5 M of HCl, and desorption time = 5 min. Under the optimum conditions, limits of detection of 50, 5, 10, 50, 10, and 500 ng/L were obtained for Co2+, Mn2+, Cu2+, Cd2+, Zn2+, and Fe3+ respectively. The relative standard deviations for determination of the selected metal ions at concentration level of 50 μg/L (n = 4) were in the range of 1.7–5.8%. Linear ranges for Co2+ and Cd2+ (0.1–250 μg/L), Cu2+ and Zn2+ (0.05–250 μg/L), Fe3+ (1–250 μg/L), and Mn2+ (0.01–25 and 50–500 μg/L) were obtained with perfect correlation coefficients (R = 0.9958–0.9996, n = 8). The applicability of the method was evaluated by the extraction and determination of the heavy metal ions in different water samples.

“…The obtained polymer, ion‐imprinted polymer, can recognize template ions with high selectivity. Due to its stability, reusability, and selectivity to target ions [1], IIP has been widely used in enrichment and separation of metal ions [2–4], especially in the fields of membranes [5] and SPE [6–8]. In addition, not only can IIP be used to extract uranium from seawater [9], but it also plays an important role in radioactive protection [10] and preparation of radionuclide [11], which is of great significance in the development of radiochemistry.…”

In this work, N,N,propyl-trimethoxysilane was prepared as a multidentate functional monomer. The 3D model of the monomer coordinating with Cu 2+ indicated that the monomer is able to provide five ligating atoms like ethylenediaminetetraacetic acid-Cu 2+ to complex with Cu 2+ .When Cu 2+ was used as a template ion, the synthesis conditions of Cu 2+ -imprinted polymers were optimized upon orthogonal design. It is interesting to find that Cu 2+imprinted polymer offers a selectivity coefficient of 192.2 when the molar ratio of Cu 2+ to monomer was exactly 1:1. That means there is no excess ligating atom in the ion-imprinted polymer and therefore, the nonspecific adsorption could be avoided.Benefiting from the excellent selectivity of Cu 2+ -imprinted polymer, even if the concentration of Zn 2+ was 25 times that of Cu 2+ , Cu 2+ -imprinted polymer still affords a high selectivity coefficient. Finally, the optimal synthesis conditions for Cu 2+imprinted polymer, except the pH, were adopted to prepare Ni 2+ -imprinted polymer, and Ni 2+ -imprinted polymer also offered satisfying selectivity to Ni 2+ . That implies this multidentate monomer is adaptable in ion imprinting and, the optimal synthesis conditions of Cu 2+ -imprinted polymer except pH are likely suitable for the imprinting of other ions besides Cu 2+ .
