“…The latest cooling heating method has been widely researched to form active polymers that can recognize several dangerous molecules in water, such as atrazine (Royani et al, 2014) , melamine (Koriyanti et al, 2020) , and caffeine (Royani et al, 2021) . Edianta et al (2023a) conducted research in measuring the concentration of Fe 3+ ions by optimizing polymer imprinted ions and utilizing Arduino Uno-based instrumentation. Novianty et al (2023) have also conducted research on ion-imprinted polymers by optimizing the effect of acid solution concentration on the Fe(III) ion extraction process to determine the number of cavities formed in Fe(III)-IIPs.…”

Fe(III)-IIPs material was prepared using a cooling-heating method with different leaching variations. The synthesis process used several chemical components, including EGDMA, MAA, and BPO as the crosslinker, functional monomer, and initiator. This study focused on the template formation process of IIPs with leaching variations, using parameters such as molarity concentration, solution mixture, and temperature to influence the amount of template formed in the polymer body. The spectra of XRD showed a widening value of FWHM as higher molarity was applied during the leaching process, with the widest one at 0.163 rad for IIPs 3 M. Fe(III) peak is located at 680-610 cm−1 or 1386-1350 cm−1 within the unleached sample, according to FTIR spectra. It also can be traced at minimum intensity in leached samples. SEM data processing showed that higher concentrations were essential in releasing Fe(III) ions from the polymer body. Meanwhile, heat treatment did not strongly impact the template formation sites of IIPs. Synthesized Fe(III)-IIPs materials had adsorption capacity, optimum time, and efficiency of 9.35 mg.g−1, 40 minutes, and 93.48%, respectively. Based on the results, Fe(III)-IIPs materials had great potential as adsorbents for removing metal pollutants from water.

Water-resistant PVA (polyvinyl alcohol) electrospun membranes with different crosslinking mechanisms were synthesized using the facile electrospinning technique. The crosslinking mechanisms were differentiated by introducing 2 different functional groups of different crosslinker agents into the molecular structure of the membrane. The evaluation of water resistance was conducted by both micro- and macro-structural analyses, such as Fourier Transform Infrared spectroscopy (FTIR), Scanning Electron Microscope (SEM), Energy Dispersive X-ray Spectroscopy (EDS), X-ray Diffraction (XRD), water contact angle (WCA), and immersion test. Infrared spectra confirmed the formation of new bands at around 1700 cm-1, which are acetal or ester groups, indicating the successful crosslinked process. Additionally, the lowered intensity of hydroxyl groups also signifies that the membrane is water-resistant. The XRD patterns showed the signature peak of PVA at the angle of 20°. Furthermore, the reduction in iron content, as shown by EDS spectra, was attributed to the surface imprinting process. SEM images displayed the formation of nanofibers, with mean diameters of 103 nm and interconnecting nanobead structures. The results showed that WCA was significantly enhanced, up to 91°, with minor loss in structure during water immersion test for 24 h. These findings confirm the hydrophobic characteristics of the membranes and their potential application in water-related fields.
