Does anyone know if it is possible to use cation membranes in a diffusion dialysis system to remove free NaOH and retain sodium aluminate (dissolved aluminium in caustic).
Is this process possible? Can the membranes withstand the 25% NaOH soln and the pH 13? Are there companies out there that manufacture such systems?
Any help on the topic is greatly appreciate.
Thankyou.
Jim
