“…Notable changes in spectrum of poly(AN- co -AA) after functionalization inveterate successful incorporation of thioamide group to the polymer surface. Similar trends were reported by other researchers [27]. After dye adsorption, the corresponding spectrum shows some changes such as shifts in absorption peaks assigned to –OH, –NH 2 and –C=S functional groups.…”

“…The band at 2244 cm −1 completely disappeared, and has been converted to –C=N– at 1614 cm −1 in TA-poly(AN- co -AA) polymer. The characteristic peaks of O-H and N-H functional groups overlapped around 3500–3200 cm −1 [26,27]. Absorption bands at 729 cm −1 and 1015 cm −1 correspond to C=S group vibrating region attached to nitrogen [27,28].…”

“…The results of zeta potential analysis show that electrostatic interactions between negatively charged TA-poly(AN- co -AA) and cationic MB dye molecule play crucial role in their high sorption capacities. Besides, TA-poly(AN- co -AA) adsorbent possess electron-rich N 2 and S atoms which favour the adsorption process as they serve as basic reactive centre for MB uptake according to [18,27].…”

The paper evaluates the adsorptive potential of thiourea-modified poly(acrylonitrile-co-acrylic acid), (TA-poly(AN-co-AA)) for the uptake of cationic methylene blue (MB) from aquatic environments via a batch system. TA-poly(AN-co-AA) polymer was synthesized through redox polymerization and modified with thiourea (TA) where thioamide groups were introduced to the surface. Fourier transform infrared (FT-IR) spectroscopy, scanning electron microscopy (SEM), CHNS and Zetasizer were used to characterize the physico-chemical and morphological properties of prepared TA-poly(AN-co-AA). Afterwards, it was confirmed that incorporation of thioamide groups was successful. The adsorption kinetics and equilibrium adsorption data were best described, respectively, by a pseudo-second-order model and Freundlich model. Thermodynamic analysis showed the exothermic and spontaneous nature of MB uptake by TA-poly(AN-co-AA). The developed TA-poly(AN-co-AA) polymer demonstrated efficient separation of MB dye from the aqueous solution and maintained maximum adsorption capacity after five regeneration cycles. The findings of this study suggested that synthesized TA-poly(AN-co-AA) can be applied successfully to remove cationic dyes from aquatic environments.

High flux PP/EVOH nanofibrous composite microfiltration membrane (P/E‐NCMM) based on polypropylene (PP) (575 nm) and polyethylene‐co‐polyvinyl alcohol (EVOH) nanofibers (248 nm) with low operation pressure for liquid filtration was fabricated by melt blending extrusion. PP nanofibers as the scaffold played a supporting role, and EVOH nanofibers filled in the PP nanofibers network structure narrowed the pore size and improved the wettability. Taking advantages of PP and EVOH nanofibers, the nanofibrous composite membrane created fascinating features for liquid filtration. The experimental results showed that the P/E‐NCMM had high average pure water flux at low operating pressure. The P/E‐NCMM with 30 wt % PP nanofibers showed high water flux [450.9 L/(m2 h)] even at very low feeding pressure (0.05 MPa) with above 95% retention for TiO2 suspension. The results indicated that the P/E‐NCMM prepared by this method had great potential for the application in liquid filtration. © 2016 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2016, 133, 43585.
