Mass transfer modeling

• A simple model describing countercurrent single-pass electrodialysis is established. • Concentration distribution along the membrane is calculated. • Influence of concentration distribution on scaling risk is discussed. A simple model based on division of electrodialyzer into the elementary units a

Polyacrylic acid gel is known for its ion chelating properties. Its poor mechanical resistance hinders its use in extraction operations. Crosslinking can improve the mechanical resistance but lowers the chelating capacity. A gel encapsulation technique has been developed to obtain a material constit
