“…The nature of the adsorption/desorption isotherms classified imprinted polymers as type IV with H3 hysteresis loops according to the recommendation of the International Union of Pure and Applied Chemistry classification of isotherms. Therefore, the imprinted polymers possessed a mesoporous structure. , The pore size distribution (total pore volume and average pore width), as well as the surface area, were calculated from the adsorption/desorption isotherm methods (see the Supporting Information Table S1). It could be seen that the surface areas of unleached IIP and leached IIP were 79.3 and 106 m 2 g –1 , respectively, and the average pore widths of unleached IIP and leached IIP were 12.3 and 12.7 nm, respectively.…”

This study presents novel chemoresistive reduced graphene oxide–ion-imprinted polymer (IIP–rGO)-based sensors for detection of lead (Pb2+) ions. The ion-imprinted polymer was synthesized by bulk polymerization and modified with a variable amount of rGO incorporated to form an IIP–rGO composite. The amount of rGO in the polymer matrix affected the sensor’s relative response, and 1:3 mass ratio produced excellent results, with a consistent trend as the concentration of Pb2+ ions increased in the solution. The decrease in relative resistance (ΔR/R o) followed an exponential decay relationship between the ΔR/R o response and the concentration of Pb2+ ions in aqueous solutions. After solving the exponential decay function, it is observed that the sensor has the upper limit of ΔR/R o >1.7287 μg L–1, and the limit of detection of the sensor is 1.77 μg L–1. A nonimprinted polymer (NIP)-based sensor responded with a low relative resistance of the same magnitude although the concentration was varied. The response ratio of the IIP-based sensor to the NIP-based sensor (ΔR/R o)IIP/(ΔR/R o)NIP as a function of the concentration of Pb2+ ions in the solution shows that the response ratios recorded a maximum of around 22 at 50 μg L–1 and then decreased as the concentration increased, following an exponential decay function with the minimum ratio of 2.09 at 200 μg L–1 but never read 1. The sensor showed excellent selectivity against the bivalent cations Mn2+, Fe2+, Sn2+, and Ti2+. The sensor was capable of exhibiting 90% ΔR/R o response repeatability in a consecutive test.

With the continuous depletion of global rhenium resources, the separation and purification of rhenium (Re) from secondary resources became very important. Herein, an imprinted composite membrane with “flexible chain” thermo‐responsive imprinted separation layer structure (Re‐TIICM) was prepared to achieve selective separation and recovery of Re from secondary resources with complex composition. Re‐TIICM's thermo‐responsive imprinted separation layer occurred sol/gel phase transition by adjusting the temperature, which effectively mitigated the trade‐off between selectivity and desorption. The structure and performance of Re‐TIICM under optimum process conditions were tested and evaluated. The results showed that Re‐TIICM exhibited a maximum adsorption capacity of 0.1036 mmol/g at 35°C, a separation degree of 4.37 (MnO4− as disturbing ions), and remained good adsorption capacity and selectivity after 9 adsorption/desorption cycles. When Re‐TIICM was applied in secondary resources, the purity of Re increased from 35.412% to 70.208% after one adsorption/desorption cycle, showing a great potential for industrial applications.
