Several hydrated forms of the oxide are known, and a colloidal variety may be obtained by the dialysis of a strong hydrochloric acid solution of sodium molybdate.
Dialysis came a few years later, then chemotherapy, then the defibrillator, then the polio vaccine; then came cloning, then a kidney transplant.
Dialysis patients advised to use bicarbonate to raise the pH of the dialysis water.
Toward the end of dialysis, I tended to just go to these restaurants armed with a handful of phosphate binders.
A study published a few years ago clearly showed a benefit to dialysis patients who took chitosan.
