CRIS Current Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishMixed 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.
