Glass ion exchange process

WebCountercurrent ion exchangers are considered continuous process equipment, although the process is actually intermittent. The solution runs for a period of time, then stops to allow a slug of resin that is moved by the hydraulic impulse to flow countercurrent to the solution. ... Ion exchange takes place in one column, while the resin in the ... WebMay 30, 2024 · In the last few years, some advances have been made in the theoretical modelling of ion exchange processes in glass. On the one hand, the equations that describe the evolution of the cation concentration were rewritten in a more rigorous manner. This was made into two theoretical frameworks. In the first one, the self-diffusion …
