Despite commonly being used as the hosts for gases, solvents and other neutral molecules, metal-organic frameworks (MOFs) have received recent attention supramolecular anion binding with a broad range of environmental biological applications. The review summarizes development this area, anion-binding MOFs categorized based on different design strategies including cationic anion-exchange capabil...
Anion exchange membranes are highly versatile and nowadays have many applications, ranging from water treatment to sensing materials. The preparation of anion exchange membranes (AEMs) from brominated poly(2,6-dimethyl-1,6-phenylene oxide) (BPPO) and methyl(diphenyl)phosphine (MDPP) for electrodialysis was performed. The physiochemical properties and electrochemical performance of fabricated me...
A novel method was developed for the preparation of highly efficient anion- and cation-exchange microHPLC columns using an on-column polymerization of methacrylates having amine or sulfonic acid functional groups onto monolithic silica capillary columns modified with 3-methacryloxypropyltriethoxysilane as the anchor groups. The chromatographic evaluation of the columns using nucleic acids, nucl...
Anion-Exchange Chromatography I. Mechanism of Separation Although anion-exchange chromatography has been used extensively to analyze acidic carbohydrates and glycopeptides, it has not been commonly used for analysis of neutral sugars. However, examination of the pKa values of the neutral monosaccharides listed in Table 1 shows that carbohydrates are in fact weak acids. At high pH, they are at l...
