“…The EDX results in Figure 3 show that 21.3 wt% of Ni(II) is present in the unleached polymer particles, whereas the spectra of the leached particles show a negligible Ni(II) peak. Furthermore, the percentage weights of carbon, oxygen and nitrogen is quite the same, confirming that during leaching (using 3.0 M HCl) only the Ni 2+ ions are leached out and not the ligand [27]. …”

“…The selection of interfering metal ions for this study was based on the similarity of chemical properties of other metals to the nickel(II) ions [27]. The selectivity of the Ni(II)-IIP for nickel in this study was much better compared to that was previously reported for some polymers [30,31].…”

“…The precision of the method for five standard solutions containing 1 µg/mL of Ni(II) ions was assessed by determining the relative standard deviation and was found to be 1.47% [27]. The detection limit defined as CLOD = 3 Sb/m, where Sb is the standard deviation of four replicate blank signals for a sample volume of 10 mL and m is the slope of the linear section of the calibration curve after pre-concentration, were found to be 1.3 ng/mL.…”

“…Among the investigated parameters, pH is the most important factor for adsorption of Ni(II) ion on the IIP particles [27]. Therefore high concentration of the hydrogen ions interfere with the rebinding of the metal ion to the cavity as the hydrogen ions also bind with the cavity, whereas a low concentration of hydrogen ions and existence of OH -usually leads to the formation of precipitates with ligands.…”

Nanoporous particles Ni(II) ion imprinted polymer (IIP), and non-imprinted polymer (NIP) in the absence of Ni(II) ion, with 18-70 nm dimensions were synthesized, and characterized by Fourier transform infrared, energy dispersive X-ray and nuclear magnetic resonance spectroscopic methods. Then, the surface area, pore size and structural composition of the products were characterized by Brunauer-Emmett-Teller and scanning electron microscope methods. Then, modified electrodes by the IIP for Ni(II) sensing and determination, were constructed and their catalytic activity were investigated by cyclic voltammetric method. Some parameters like desorption solvent, amount of sorbent, pH and contact time were optimized, and the measurements were all conducted under optimal conditions. The optimum pH for maximum sorption was obtained 7.8. In the optimum conditions, the maximum sorbent capacity of the IIP was obtained 371.9 µM/g. The limit of detection and relative standard deviation (n = 5) were obtained 1.3 ng/mL and 1.47%, respectively. The pre-concentration procedure revealed a linear curve within the concentration range of 10-6000 ng/mL and a good linearity with squared correlation coefficient of r 2 0.9991 was achieved. The method was applied successfully for determination of Ni(II) ion in petrochemical samples.

This article explains how composite thin films, that are made of both cross‐linked poly(methyl methacrylate) (PMMA) and reinforced with multi‐walled carbon nanotube (CNTs), are designed, fabricated and developed for selective cationic sensing applications. The C‐PMMA‐CNTsa‐e nanocomposites were prepared by in situ cross‐linking reaction technique using 4,4′‐diaminobiphenyl (DABP) as the cross‐linking agent. Variable loading of CNTs varied from 2 to 40 wt% was utilized during the cross‐linking process. The nanocomposite films have been structurally characterized by Fourier transform infrared and XRD and the results confirm the incorporation of CNTs in the C‐PMMA matrix, while the dispersion of CNTs in C‐PMMA was characterized using SEM and TEM. The dispersion of CNTs in the composites was excellent, even at high CNTs loading as indicated by SEM and TEM. TEM images of C‐PMMA‐CNTs nanocomposites reveal a core‐shell structure in which CNTs as the core and C‐PMMA as the shell. The thermal features of the nanocomposite films were investigated through their TGA and DTG data. The results confirmed the importance of CNTs content in enhancing the thermal stability of the nanocomposite. The desired yttrium (Y3+) cation sensor was fabricated using glassy carbon electrode coating with a thin uniform layer of synthesized C‐PMMA‐CNTse nanocomposite. A calibration curve was plotted as current vs. concentration of Y3+ ion. The resulted calibration curve is found linear over linear dynamic range of 0.1 nM–0.1 mM. The slope of calibration curve is used to measure the sensitivity (27.2943 μA μM−1 cm−2), limit of detection (3.48 ± 0.17 pM), and limit of quantification (LOQ; 11.6 ± 0.57 pM) of Y3+ cation. It is also found as reliable sensor to detect Y3+ ion in real environmental samples. Considering the contamination of environment, this research might be reliable way for the development of future prospective cationic sensor for the safety of healthcare and ecological fields. POLYM.
