Ionsiv F-80 and Ionsiv W-85: Molecular Sieve Zeolite NH4+ Ion Exchangers for Removal of Urea Nitrogen
New molecular sieve zeolite ion exchangers with high NH4 + exchange selectivities and capacities have been discovered and developed for use in a variety of applications. Preliminary tests show the LINDE IONSIV F-80 and IONSIV W-85 ion exchangers provide high NH4 + capacities in synthetic solutions similar in composition to blood serum or dialysate solutions.
The use of these new IONSIV NH4 + exchangers in conjunction with urease enzyme hydrolysis promises to provide significant improvements in urea removal for use in treatment of chronic renal disease.
