“…The possibility to design micro and nanoparticles with predetermined features has favored the use of MIPs in many applications for the control and removal of CECs. For example, MIPs are widely used in detection and analysis of CECs, as well as sensing [15], sample pretreatment [109], and chromatographic fields [110]. In particular, in the analytical field, these polymers have seen a significant step forward in the samples' pretreatment, which is enriched and eluted in a new solution, avoiding the effects of the real matrix [111].…”

Contaminants of emerging concern (CECs) are one of the main barriers in the water cycle as they limit the water reuse due to their adverse effects on humans and the ecosystem. Natural and/or engineered ecosystems, such as conventional wastewater treatment processes, are not designed to remove CECs and contribute to the bioaccumulation in organisms considering high volumes of treated water discharges. The adoption of innovative solutions to upgrade urban water cycle facilities has gained relevance for the removal of these substances from final effluents. Molecularly imprinted polymers (MIPs) show promising selective removal toward a wide range of CECs. However, this solution is still limited to lab/bench scale and needs to be critically analyzed and assessed for possible scale-up in real environment. Therefore, in this review, an overview of the fate and occurrence of CECs in wastewater is initially reported together with the state-of-the-art in adsorption mechanisms to remove these compounds. In the central part of the paper, an evaluation of MIPs synthesis and their status in removing CECs from water matrix are presented. An upscaling pathway of MIPs column from lab-to pilot-scale is given to be applied for enhanced CECs removal and safe water reuse in irrigation/fertigation. Finally, possible integrations of MIP columns to real wastewater treatment facilities is discussed and advantages and disadvantages of the potential solutions are addressed to enhance their sustainability.

“…Currently, the MIPs have attracted increasing attentions for chromatographic analysis with selective recognition for the target molecules [79,80]. MIPs are usually synthesized through polymerizing reaction of functional monomers around a template molecule, producing a highly crosslinked three-dimensional network structure.…”

Deep eutectic solvents have received increasing attention over the past decade, and the green and versatile nature makes them important media for developing environmentally friendly and sustainable technologies. In addition to act as green alternatives to traditional organic solvents, deep eutectic solvents offer tremendous opportunities to produce different kinds of emerging functional materials. The present review highlights the recent development and applications of deep functional materials based on deep eutectic solvents as novel adsorbents for diverse analytes in complex matrices. The type, preparation, and unique properties of deep eutectic solvents, the synthesis of deep eutectic solvent derived materials, as well as their applications in chromatographic separation are described. We aim to demonstrate that deep eutectic solvents not only allow the design of eco-friendly extraction processes but also open straightforward access to advanced materials in sample preparation.

“…MIPs are by nature selective materials for sample preparation and detection, applied in many different approaches such as SPE and electrochemical devices [107], and they have gained a lot of visibility in miniaturized sample preparation techniques such as SPME and stir-bar sorptive extraction (SBSE) [110,111] and also with other approaches in Green Analytical Chemistry. In one of these examples, the combination of microwave-assisted extraction (MAE) and molecularly imprinted SPE (MISPE) was developed for the determination of BPA in food [23].…”

Bisphenol A is a synthetic compound widely used in industry, in the production of polycarbonate, epoxy resins, and thermal paper, among others. Its annual production is estimated at millions of tons per year, demonstrating its importance. Despite its wide application in various everyday products, once in the environment (due to its disposal or leaching), it has high toxicity to humans and animal life, and this problem has been well known for years. Given this problem, many researchers seek alternatives for its monitoring in matrices such as natural water, waste, food, and biological matrices. For this, new advanced materials have been developed, characterized, and applied in creative ways for the preparation of samples for the determination of bisphenol A. This article aims to present some of these important and recent applications, describing the use of molecularly imprinted polymers, metal and covalent organic frameworks, ionic liquids and magnetic ionic liquids, and deep eutectic solvents as creative solutions in sample preparation for the long-standing problem of bisphenol A determination.
