“…Figure 8 illustrates the synthesis scheme of the NM/CMKCNi(II)IIP adsorbent through several steps. CMKC, which has bound Ni(II), was crosslinked with BADGE, this binding model has been proposed by previous researchers, who conducted cross-linking experiments of carboxymethyl cellulose polymers with BADGE [26]. The CMKC crosslinking reaction in this study proceeded as the reaction is shown in Figure 9.…”

“…The printed polymer technique produces polymers with specific templates, which are recognized by the ion/similar molecules contacted after ion imprinting [25]. [26] carried out cross-linking of carboxymethyl chitosan with bisphenol A diglycidyl ether (BADGE); this cross-linking brought the carboxymethyl chitosan carbonyl groups closer together which allowed the carbonyl lone pair to form a covalent bond to bind to the Pb(II) metal ion. The binding of metal ions is followed by the release of Pb(II) ions which are bound to the polymer, resulting in the formation of gaps printed by Pb(II) ions, on polymers.…”

Nickel(II) ions are carcinogenic water pollutants. To increase the accuracy of instrumental analysis of Ni(II) content, several analytical preparation methods have been developed, including solid phase adsorption extraction. The development of magnetic solid phase extraction adsorbents for metal ions is required, to support the application of magnetic solid phase adsorption as a method of separating metal ions in aqueous samples. This research describes the synthesis of Magnetic Solid Phase Extraction adsorbents as Ni(II) ion adsorbents, nano magnetite/carboxymethyl kappa-carrageenan (CMKC) crosslinked bisphenol A diglycidyl ether (BADGE) imprinted Ni(II)-IIP ion composites. This research was carried out in several stages, synthesis and characterization of nano magnetite (NM), synthesis and characterization of CMKC, and synthesis of NM/CMKCNi(II)-IIP adsorbents. The results of the synthesis were analyzed for morphological characteristics, magnetic strength, spectral characteristics, crystallinity, and composition using SEM, FTIR, XRD, and XRF instruments. The adsorption ability of Ni(II) of the adsorbent was tested. Determination of Ni(II) ion content in the sample before and after adsorption was carried out using a flame atomic absorption spectrophotometer (FAAS). Based on the results of spectral character analysis, crystal diffraction patterns, magnetic strength, and morphology, it is confirmed that nano-magnetite has been successfully synthesized. The diameter of the nano magnetite grains is 21.8 nm, the adsorbent NM/CMKCNi(II)-IIP has magnetic properties and wavy surface morphology. The optimum adsorption ability of Ni(II) for the NM/CMKCNi(II)-IIP composite was 2.44 mg Ni(II)/g adsorbent. To evaluate the tendency of the adsorption ability of the adsorbent towards Ni(II) ions in the presence of competitor ions, the adsorption ability of the adsorbent to adsorp Ni(II) ions in samples containing Ni(II) ions, Pb(II) ions and a mixture of Ni(II) ions. and Pb(II) were determined, based on the results of the analysis, the ability of the adsorbent to adsorb Ni(II) ions was higher than the ability of the adsorbent to adsorb Pb(II) ions, in all types of samples.

In this study, the microreactor system was investigated and compared with the batch-wise system as rapid and effective extractive Pb(II) separation over Fe(III), Cu(II) and Zn(II) with tetraacetic acid calix[4]arene. By using a microreactor system, the Pb(II) extraction percentages reached the maximum of 73, 89 and 100% in 8 sec residence time at equilibrium pH of 2.00, 2.25 and 2.50, respectively. The stripping percentage was 92% at 8 sec residence time by using a microreactor system with 2.0 M HNO3 as a stripping reagent. Complete separation of Pb(II) over Fe(III), Cu(II) and Zn(II) ions with the tetraacetic acid calix[4]arene in a competitive metal system was achieved at pH 2.00. However, the batch system required 24 h to reach the equilibrium for both extraction and stripping processes. The results suggested that the microreactor system enhanced the Pb(II) extraction and stripping rate up to 104 times faster than the batch-wise system.

Karboksimetil kitosan menunjukkan potensi untuk digunakan sebagai polimer induk bagi aplikasi elektrolit polimer pepejal. Kesan garam litium nitrat terhadap sifat elektrokimia elektrolit polimer pepejal berasaskan karboksimetil kitosan telah dijalankan. Elektrolit polimer pepejal berasaskan karboksimetil kitosan disediakan melalui teknik pengacuan larutan dengan nisbah garam litium nitrat (LiNO 3) yang berbeza. Pencirian filem telah dijalankan dengan menggunakan spektroskopi inframerah transformasi Fourier-pantulan penuh kecil (ATR-FTIR) dan Spektroskopi Impedans Elektrokimia (EIS) bagi penentuan interaksi kimia dan sifat elektrokimia polimer elektrolit tersebut. Spektrum ATR-FTIR menunjukkan ion litium cenderung untuk berinteraksi dengan kumpulan karbonil dan kumpulan ester dalam struktur karboksimetil kitosan. Kekonduksian ion tertinggi yang dicapai adalah 8.44 × 10-4 S cm-1 dengan kepekatan garam 30 bt. % LiNO 3 pada suhu bilik dan 5.25 × 10-3 S cm −1 pada suhu 70°C. Filem karboksimetil kitosan-30% LiNO 3 mencapai kestabilan secara elektrokimia sehingga 2.94 V. Keputusan kajian yang diperoleh menunjukkan elektrolit polimer pepejal berasaskan karboksimetil kitosan memberi satu tarikan baru bagi aplikasi bateri ion litium.
