Summary: A new method was developed to synthesize water-compatible hierarchically porous molecularly imprinted polymers (HP-MIPs) for efficient removal of organic pollutants from wastewater. The integration of a metal-organic gel (MOG) modulator and template imprinting defects significantly improved the specific template binding affinity of HP-MIP in water, demonstrating its effectiveness in removing sildenafil.

Summary: Double template magnetic molecularly imprinted polymers (CBZ/OXC-MIPs) were successfully prepared with specific recognition for carbamazepine (CBZ) and oxcarbazepine (OXC). The preparation process was optimized for the ratio of template molecules to functional monomer, crosslinker and solvent dosages, and the ratio of CBZ to OXC. The adsorption experiments showed that CBZ/OXC-MIPs exhibited specific recognition and the adsorption process followed the Freundlich model and pseudo-second-order kinetic model. The selective adsorption of CBZ/OXC-MIPs was mainly attributed to van der Waals forces, hydrogen bond, and electrostatic interaction.

Summary: In this study, ZIF-7-modified magnetic graphene-based matrix materials (MRGO@ZIF-7) were prepared using Zn(NO3)(2)center dot 6H(2)O as the metal source. MRGO@ZIF7-MIP, a ZIF-7 modified magnetic graphene-based molecular imprinting complex, was successfully synthesized using bisphenol A (BPA) as the template molecule. The obtained materials were characterized using various techniques, and the adsorption and recognition abilities of MRGO@ZIF7-MIP for BPA were investigated.

Summary: A molecularly imprinted triazine-based conjugated microporous polymer composite was developed for the solid-phase extraction (SPE) of three phenolic endocrine disrupting chemicals in beverages. The method involved derivatization and detection by gas chromatography-electron capture detector. Under optimized conditions, the limits of detection of the analytes ranged from 0.12 to 1.20 μg L-1 and the linear response range was 0.40-50.0 μg L-1. The method showed good recoveries and potential for the monitoring of trace phenolic endocrine disrupting chemicals in real beverage samples.

Summary: A molecularly imprinted polymer was constructed for the first time using the dummy imprinting strategy with homopiperonylamine as the dummy template. The polymer showed high selectivity towards amphetamine-type stimulants and could rapidly adsorb them from water. It also exhibited low matrix effects and could be used for the pretreatment of these stimulants in alcoholic and nonalcoholic beverages.

Summary: Endocrine-disrupting chemicals (EDCs) are pollutants that have adverse effects on water quality even at low concentrations. These pollutants enter the human system through contaminated air, water, and food, and can disrupt the endocrine systems of humans and wildlife. To improve water quality and protect the ecosystem, it is important to develop effective and cost-efficient removal techniques for EDCs.

Summary: Four types of molecularly imprinted TiO2 photocatalysts exhibited different selectivity for sulfonamide antibiotics. The degradation rate constants of SD ranged from 0.0789 to 0.1051 min-1, while the removal rate constants of SMX varied from 0.1076 to 0.5848 min-1. The major transformation pathways of SAs involved bond cleavage, hydroxylation, ring-opening, oxidation, and deamination. The novel MIP-TiO2/SN and MIP-TiO2/AN showed excellent catalytic abilities with less byproducts formed.

Summary: Rapid urbanization, industrialization, and population growth have led to an increased release of emerging contaminants, including endocrine-disrupting compounds (EDCs), into the aquatic environment. This poses a threat to human health and the environment, even at low levels. Therefore, there is an urgent need for new water treatment technologies to effectively remove EDCs. Calcium-based metal-organic frameworks (Ca-MOFs) are promising adsorbents due to their stability, biocompatibility, and low cost compared to traditional porous materials. Ca-MOFs have shown the ability to selectively extract a significant amount of contaminants, making them suitable for water purification. This review discusses the potential of Ca-MOFs in adsorbing EDCs, including their preparation methods, adsorption mechanisms, removal capacity, water stability, and recyclability. It supports future efforts in synthesizing biocompatible MOFs as an environmental treatment technology to improve water quality and human health.

Summary: The nano-sized magnetic ion-imprinted polymers (MIIPs) synthesized using chitosan showed high sorption selectivity for Ni(II) and could efficiently recover the adsorbed ions. The sorption process was quick, endothermic, and could be described by Langmuir isotherm model and pseudo-second-order kinetic model. MIIPs proved to be a suitable adsorbent for selective removal and recovery of low-concentration Ni(II) ions from wastewaters.
