“…The large number of crosslinkable hydroxyl groups as well as the strong interfacial activity of polyphenols make catechin a potential substituent to commonly used harmful phenols [23]. In our previous work [25] we used Morin, a very similar polyphenol, as one of the reactants. In this work we replaced not only the Morin, but also the hydrazine cross-linked polyacrylonitrile support with an environmentally friendly biopolymer support.…”

In this work, a novel thin-film composite membrane composed of a polyester film on a cellulose support was successfully synthesised. The polyester film was formed from the interfacial reaction between catechin, a bio-derived poly-phenol, and terephthaloyl chloride (TPC). The cellulose support was prepared by non-solvent induced phase separation from a weight cut-off of around 500 g mol -1 . The membrane was stable in DMF over 30 days with no significant change in performance. The membrane has potential application in the food and pharmaceutical industries.

BACKGROUND Pb(II)‐containing wastewater causes serious pollution in our daily life. Adsorption is the technique most often used to remove heavy metals from aqueous solution. For improving the removal efficiency of Pb(II) ions from aqueous solution, adsorbent materials and the functionalization method of the adsorbent need to be further studied. RESULTS A novel Schiff's base functionalized bio‐material (DAS2‐AT) with two tridentate coordinated units was synthesized by the reaction of 2‐acetylthiophene and modified dialdehyde starch (DAS‐NH2) for the adsorption of Pb(II) ions from aqueous solution. Experimental results demonstrated that the DAS2‐AT exhibited high adsorption capacity and selectivity towards Pb(II), and the maximum adsorption capacity was up to 203 mg g−1. The adsorption isotherms and kinetic of Pb(II) ions on the DAS2‐AT were correlated well with the Langmuir isotherm model and Pseudo‐second‐order model. Moreover, thermodynamic analysis indicated that the adsorption process is spontaneous and endothermic. Desorption and regeneration experiments indicated that DAS2‐AT has good reusability. Besides that, the adsorbent displayed good affinity of DAS2‐AT towards Pb(II) ion in the presence of Cr(VI), Zn(II), and Ni(II) ions. CONCLUSION The bio‐adsorbent (DAS2‐AT) displayed good adsorption performance to remove Pb(II) ions from aqueous solution. DAS2‐AT gave a potential application as a low‐cost and effective adsorbent. © 2021 Society of Chemical Industry

“…Among them, tannic acid [76][77][78][79][80], quercetin [81], morin hydrate [82], cyclodextrin [83][84][85], chitosan [86], and vanillin [87] played a well role as a reactive material, resulting in the formation of the stable selective layer having great performance. However, most of approaches have changed only one monomer.…”

Organic solvent nanofiltration (OSN) has been recognized as an eco-friendly separation system owing to its excellent cost and energy saving efficiency, easy scale-up in the narrow area and mild operation conditions. Membrane properties are the key part in terms of determining the separation efficiency in the OSN system. In this review paper, the recently reported OSN thin-film composite (TFC) membranes were investigated to understand insight of membrane materials and performance. Especially, we highlighted the representative study concepts and materials of the selective layer of OSN TFC membranes for non-polar solvents. The proper choice of monomers and additives for the selective layer forms much more interconnected voids and the enhanced microporosity, which can improve membrane performance of the OSN TFC membrane with reducing the transport resistance. Therefore, this review paper could be an important bridge to connect with the next-generation OSN TFC membranes for non-polar solvents.
