“…Moreover, utilizing zinc oxide nanoparticles enhanced the char yield of prepared films. Although some works on PVC and ZnO have been carried out, but few reports considered adding zinc oxide to PVC for special purposes such as UV absorption, antibacterial properties [20,21] and separation process [22][23][24].…”

In this study, soluble in water poly(azomethine-ester)s (PAEs) were synthesized via elimination reactions of aromatic dihydroxy compounds containing imine bonding with terephthaloyl chloride. The structures of Schiff bases (SBs) and PAEs containing different aliphatic chains were confirmed by FT-IR, 1 H-NMR, 13 C-NMR and UV-Vis analyses. Physicochemical properties of the new polymers were characterized. Thermal properties of the compounds were investigated by TGA-DTA, DMA and DSC. According to TGA measurements, the starting degradation temperatures (T on ) of P-1, P-2, P-3, and P-4 poly(azomethine-ester)s were found as 255°C, 232°C, 222°C, and 221°C, respectively. The starting degradation temperatures of the poly(azomethine-ester)s were higher than their Schiff base compounds. According to dynamical mechanical analysis (DMA) measurements, glass transition temperature (T g ) of P-1, P-2, P-3, and P-4 poly(azomethine-ester)s were found as 95°C, 138°C, 140°C, and 145°C, respectively. The morphological and topographic properties of the PAEs containing azomethine linkage in the main chain were investigated by FE-SEM and AFM, respectively. The molecular mass distributions of PAEs were determined by gel permeation chromatography (GPC). Electrochemical (E g ) and optical band gap (E opt g ) values of the prepared SBs and PAEs were calculated from cyclic voltammetry (CV) and UV-Vis analyses. The electrochemical band gap (E g ) values of P-1, P-2, P-3 and P-4 were found as 2.44 eV, 2.41 eV, 2.39 eV and 2.39 eV, respectively, from the cyclic voltammetry.

“…Ion-exchange method may have the various advantages such as regeneration capability of ion-exchange materials, low cost, pH independence, high selectivity, etc. Various types of ion-exchange materials including inorganic, organic, and composite ion-exchange materials are being used for the wastewater treatment worldwide [24][25][26][27][28][29]. Nowadays, organic-inorganic-type composite ion-exchange materials, inorganic and organic ionexchange materials are being extensively used for wastewater treatment without studying the validity of ion-exchange mechanism [30][31][32].…”

Explicit Nernst-Planck approximation is used to study the kinetics of H(I)-metal ion-exchange processes for ions having different effective diffusion coefficients, that is, for non-isotopic exchange process. Kinetic studies of four heavy metal ions (Cd 2+ , Co 2+ , Cu 2+ , and Pb 2+ ) of environmental importance on the surface of acetonitrile stannic(IV) selenite composite cation exchanger were carried out successfully. On the basis of kinetic studies, various physical parameters, that is, fractional attainment of equilibrium U(τ), self-diffusion coefficients (D o ), energy of activation (E a ), and entropy of activation (ΔS*) are estimated to evaluate the mechanism of ion exchange on the surface of composite ion-exchange material. The activation entropy and energy revealed that the greater degree and minimum energy was achieved during forward ion-exchange process. The results revealed that the kinetic studies are very important for the economic and industrial applications of ion-exchange materials.
