“…One of the best ways to decrease the level of Mn(II) ions in the environment is their adsorption onto Mn(II)-IIPs (see Table S8 ) [ 156 , 157 , 158 ]. For this aim, an interesting approach was recently developed by Aravind and Mathew who fabricated electrochemical sensors for Mn(II) ions by the modification of a platinum electrode using the IIP technique, with and without vinyl functionalized MWCNTs, which come with their high surface area, electrical, chemical, and mechanical stability, as well as easy electron transfer [ 158 ]. The functional monomer was MAA and the cross-linker was MBAAm.…”

“…To evaluate the selectivity of the Pt-MWCNTs-Mn(II)-IIP sensor, the sorption of Mn(II) in the presence of Co(II), Fe(II), and Cr(III) as competitive ions was investigated. It was found that only Mn(II) ions exhibited a redox peak current response while the other metal ions did not show any current response [ 158 ].…”

The introduction of selective recognition sites toward certain heavy metal ions (HMIs) is a great challenge, which has a major role when the separation of species with similar physicochemical features is considered. In this context, ion-imprinted polymers (IIPs) developed based on the principle of molecular imprinting methodology, have emerged as an innovative solution. Recent advances in IIPs have shown that they exhibit higher selectivity coefficients than non-imprinted ones, which could support a large range of environmental applications starting from extraction and monitoring of HMIs to their detection and quantification. This review will emphasize the application of IIPs for selective removal of transition metal ions (including HMIs, precious metal ions, radionuclides, and rare earth metal ions) from aqueous solution by critically analyzing the most relevant literature studies from the last decade. In the first part of this review, the chemical components of IIPs, the main ion-imprinting technologies as well as the characterization methods used to evaluate the binding properties are briefly presented. In the second part, synthesis parameters, adsorption performance, and a descriptive analysis of solid phase extraction of heavy metal ions by various IIPs are provided.

“…MWCNTs-IIPs had high selectivity for Cd-Cu mixtures, relatively high selectivity for Cd-Ni mixtures, and low selectivity for Cd-Zn mixtures. In 2019, they synthesized Mn 2+ IIP and composited with vinyl functionalized-MWCNTs by free radical polymerization to prepare an electrochemical sensor (Pt-MWCNTs-Mn(II)-IIP) for the detection of Mn 2+ [ 94 ]. The LOD of the electrochemical sensor was investigated with DPV and found to be 0.0138 μM, and the imprinted adsorbent showed higher selectivity and specificity for Mn 2+ compared to other metal ions.…”

Heavy metal ions (HMIs) pose a serious threat to the environment and human body because they are toxic and non-biodegradable and widely exist in environmental ecosystems. It is necessary to develop a rapid, sensitive and convenient method for HMIs detection to provide a strong guarantee for ecology and human health. Ion-imprinted electrochemical sensors (IIECSs) based on nanomaterials have been regarded as an excellent technology because of the good selectivity, the advantages of fast detection speed, low cost, and portability. Electrode surfaces modified with nanomaterials can obtain excellent nano-effects, such as size effect, macroscopic quantum tunneling effect and surface effect, which greatly improve its surface area and conductivity, so as to improve the detection sensitivity and reduce the detection limit of the sensor. Hence, the present review focused on the fundamentals and the synthetic strategies of ion-imprinted polymers (IIPs) and IIECSs for HMIs detection, as well as the applications of various nanomaterials as modifiers and sensitizers in the construction of HMIIECSs and the influence on the sensing performance of the fabricated sensors. Finally, the potential challenges and outlook on the future development of the HMIIECSs technology were also highlighted. By means of the points presented in this review, we hope to provide some help in further developing the preparation methods of high-performance HMIIECSs and expanding their potential applications.

Application of Molecularly Imprinted Polymers in the Analysis of Waters and Wastewaters

The increase of the global population and shortage of renewable water resources urges the development of possible remedies to improve the quality and reusability of waste and contaminated water supplies. Different water pollutants, such as heavy metals, dyes, pesticides, endocrine disrupting compounds (EDCs), and pharmaceuticals, are produced through continuous technical and industrial developments that are emerging with the increasing population. Molecularly imprinted polymers (MIPs) represent a class of synthetic receptors that can be produced from different types of polymerization reactions between a target template and functional monomer(s), having functional groups specifically interacting with the template; such interactions can be tailored according to the purpose of designing the polymer and based on the nature of the target compounds. The removal of the template using suitable knocking out agents renders a recognition cavity that can specifically rebind to the target template which is the main mechanism of the applicability of MIPs in electrochemical sensors and as solid phase extraction sorbents. MIPs have unique properties in terms of stability, selectivity, and resistance to acids and bases besides being of low cost and simple to prepare; thus, they are excellent materials to be used for water analysis. The current review represents the different applications of MIPs in the past five years for the detection of different classes of water and wastewater contaminants and possible approaches for future applications.
