  • Sodium bicarbonate containing precipitate-free dialysis solutions
    Patent number: 5211643
    Abstract: Dialysis solutions for hemodialysis and the like, are prepared by addition of sufficient acid to lower the pH of a sodium carbonate solution to less than 7.6 under conditions which will retain the carbon dioxide generated by such acid addition and mixing the thus produced solution with a solution of the other ions required in such a dialysis solution, again under conditions which will retain the carbon dioxide, to provide a dialysis solution which, under working conditions, will not cause finely divided precipitates of calcium carbonate to form.
