Ion-capture electrodialysis using multifunctional adsorptive membranes

One-step purification and desalination The of water for drinking purposes can require multiple filtration steps technologies to remove contaminants such as salts heavy metals. Some could have value if recovered, but these are often discharged in the waste streams. Uliana et al. describe a general approach fabrication robust, tunable, adsorptive membranes through incorporation porous aromatic framework (PAF) nanoparticles into ion exchange those made from sulfonated polymers. Salts removed using series cation anion membranes, PAF particles be selected capture specific target ions, copper, mercury, or iron. This allows simultaneous decontamination water.
