Cheers Everyone.
I was seeing some uses of ionic exchange to recover NH4 by ionic exchange with other cations in a specific matrix. And it brought me to question what drives an ionic exchange to be better towards an ion in solution and not so good to another?
I thought maybe the charge of the cation would influence but maybe is not so relevant as here Article Ammonium removal using ion exchange and biological regeneration
K and Ca are ahead of Na and Mg. Maybe the hydration radius as an important role in it instead? And can pH of the solution where ionic exchange is done affect also the selectivity of the ionic exchange knowing it can affect the lattice charge of the matrix?Is there a way we can estimate this? or just by trial?
