BPPO-Based Anion Exchange Membranes for Acid Recovery via Diffusion Dialysis
To reduce the environmental impact of acids present in various industrial wastes, improved and robust anion exchange membranes (AEMs) are highly desired. Moreover, they should exhibit high retention of salts, fast acid permeation and they should be able to operate with low energy input. In this work, AEMs are prepared using a facile solution-casting from brominated poly-(2,6-dimethyl-1,4-phenyl...
متن کاملSulfuric acid recovery from titanium white (pigment) waste liquor using diffusion dialysis with a new series of anion exchange membranes — static runs
In this paper, a new series of anion exchange membranes have been produced from linear engineering plastics poly(2,6dimethyl-1,4-phenylene oxide) (PPO) by conducting the processes of bromination, chlomethylization and amination. By using this series of membranes, the runs of sulfuric acid recovery from titanium white waste liquor were experimentally conducted. The effects of some important fact...
متن کاملStudy the Transport Properties of Anion and Cation Exchange Membranes toward Various Ions Using Chronopotentiometry
The transport properties of various anion and cation exchange membranes were studied in different electrolyte solutions using chronopotentiometry technique to get insight about the influence of the counter ion on the transport properties of the membranes. The investigated samples include heterogeneous ion exchange membranes varying in the functionality of fixed charged gro...
متن کاملElectrodialysis Heterogeneous Anion Exchange Membranes Filled with TiO2 Nanoparticles: Membranes' Fabrication and Characterization
In the current research, polyvinylchloride based mixed matrix heterogeneous anion exchange membranes were prepared by a solution casting technique. Titanium dioxide nanoparticles were also utilized as inorganic filler additive in the membrane fabrication. The effect of TiO2 nanoparticles concentration in the casting solution on the membrane physico-chemical properties was studied. Membrane wate...
متن کاملRegeneration Studies of Anion-Exchange Chromatography Resins
LEVEL: INTERMEDIATE C hromatography columns can become contaminated by a variety of protein and nonprotein species during a purification campaign. Consequences of column contamination include an increase in backpressure, loss of signal resolution, altered product yield, and medium discoloration. Common chromatographic contaminants include • residual proteins • nucleic acids • lipids • endotoxin...
