• Theory for ion transport in multicomponent electrolytes electrodialysis. Selective removal of nitrate over chloride is observed. Strategies to increase selectivity are evaluated. Increasing the membrane thickness results an increased selectivity. Decreasing charge density We analyze selective anions electrodialysis (ED) from a mixture where all ions monovalent, both experimentally, and by mod...

Contamination of toxic metals in the aquatic environment is one of the most debated problems in the world with industrial development. Thus, the minimization and recovery of harmful pollutants such as heavy metals in natural environment is very significant [1]. Various treatment technologies such as ion exchange, precipitation, ultrafiltration, reverse osmosis and electrodialysis have been used...

Membrane electrolysis (ME) is the only commercial technology using ion-exchange membranes for chromic acid recycling and recovery. On one hand, the technology has a number of promising advantages, but on the other hand, it has not yet gained common acceptance probably due to a lack of operation stability and efficiency. Published results of the research can be divided into three categories: lab...

In this study different membranes were produced, aiming to evaluate their use in electrodialysis. These membranes were produced using conventional polymer (high-impact polystyrene) and polyaniline. The membrane characterization was done by FTIR spectroscopy, scanning electron microscopy (SEM), and thermogravimetry (TGA). The studies of the zinc and proton extraction ionic transport through the ...

The need to treat wastewater in a sustainable way minimalize contamination and maximize the recovery of nutrients is widelyrecognized. focus mainly on removal because eutrophication problems receiving waters,limitations mining resources high costs affiliated with nutrient production. Removal also growing problemfor water authorities, as authorities often tighten standards discharged waters avoi...
