Here, the preparation of a new, functional anion-exchange membrane (AEM), containing guanidinium groups as the anion-exchanging sites (Gu-100), is described as well as the membrane characterization by XPS, water uptake, permselectivities, and elec. resistances. The functional membrane was also used in pH-dependent electrodialysis experiments using model dairy wastewater streams. The properties of the new membrane are compared to those of a com. available anion-exchange membrane bearing conventional quaternary ammonium groups (Gu-0). Guanidinium was chosen for its specific binding properties toward oxyanions: e.g., phosphate. This functional moiety was covalently coupled to an acrylate monomer via a facile two-step synthesis to yield bulk-modified membranes upon polymerization Significant differences were observed in the electrodialysis experiments for Gu-0 and Gu-100 at pH 7, showing an enhanced phosphate and citrate transport for Gu-100 in comparison to Gu-0. At pH 10 the difference is much more pronounced: for Gu-0 membranes almost no phosphate and citrate transport could be detected, while the Gu-100 membranes transported both ions significantly. We conclude that having guanidinium groups as anion-exchange sites improves the selectivity of AEMs. As the presented monomer synthesis strategy is modular, we consider the implementation of functional groups into a polymer-based membrane via the synthesis of tailor-made monomers as an important step toward selective ion transport, which is relevant for various fields, including water treatment processes and fuel cells.3-Aminopropan-1-ol(cas: 156-87-6Safety of 3-Aminopropan-1-ol) was used in this study.
3-Aminopropan-1-ol(cas: 156-87-6) belongs to anime. Many important products require amines as part of their syntheses. Methylamine is utilized in the production of the analgesic meperidine (trade name Demerol) and the photographic developer Metol (trademark), and dimethylamine is used in the synthesis of the antihistamine diphenhydramine (trade name Benadryl), the solvent dimethylformamide (DMF), and the rocket propellant 1,1-dimethylhydrazine. The synthesis of the insect repellent N,N-diethyl-m-toluamide (DEET) incorporates diethylamine while that of the synthetic fibre Kevlar requires aromatic amines.Safety of 3-Aminopropan-1-ol
