## Abstract 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.

✦ Synopsis
Commercially available collagen membrane was evaluated as a hemodialysis membrane in the Kolff quad-coil artificial kidney. The inherent physical weakness of the membrane was strengthened by a double-screen support substructure in a coil. Greater metabolite clearance and ultrafiltration (over four times) were demonstrated with the double-screen-supported collagen coil than with either cellophane or cuprophane membrane supported by the same double-screen support substructure.
