Membrane capacitive deionization (MCDI) is a promising technique to achieve desalination of low-salinity water resources. The primary requirements for developing and designing materials MCDI applications are large surface area, high wettability water, conductivity, efficient ion-transport pathways. Herein, we synthesized ionic covalent organic nanosheets (iCONs) containing guanidinium units tha...

Most commercial anion exchange membranes (AEMs) deploy quaternary ammonium moieties. Alternative cation moieties have been explored in AEMs for fuel cells, but there are no studies focused examining alternative tethered cations ionic separations—such as organic acid transport via electrodialysis. H-cell and conductivity experiments demonstrate that benzyl 1-methyl imidazolium groups polysulfone...

nitrate is an anion of major importance particularly in biological areas. excessive amounts in water supplies indicate pollution from sewage or agricultural effluents. the effects of excessive quantities of nitrate in water are well known. in this research structural modification of natural clinoptilolite by isomorphic substitution was performed. isomorphously substituted zeolite was prepared u...
