Mixed Matrix Membrane Adsorbers (MMMAs) based on Cellulose Acetate (CA) were prepared and tested for the removal of uremic toxins from spent dialysate aqueous streams from hemodialysis treatments. MMMAs were fabricated and modified with a natural zeolite, ZUF, to enhance the affinity towards urea, creatinine and uric acid. Water permeability tests and batch adsorption tests were performed on the prepared MMMAs, obtaining encouraging results. The removal capacity of the pure CA membranes is improved after addition of ZUF by factors as high as 83% for urea and up to 28% for creatinine.

Water permeability tests and batch adsorption tests were performed on the prepared MMMAs, obtaining encouraging results. The removal capacity of the pure CA membranes is improved after addition of ZUF by factors as high as 83% for urea and up to 28% for creatinine.File in questo prodotto:
