Cellulosic ion-exchange membranes for hemodialysis.

The application of cellulosic ion-exchange membranes to hemodialysis was studied in vitro. The membranes were prepared by radiation-grafting methacrylic acid and vinylpyridine to films of DuPont cellophane PD-215 to produce cation-exchange and anion-exchange membranes, respectively. Solutions of urea, creatinine, glucose, and uric acid were studied for… (More)
