Abstract
An attempt to observe the radical scavenging effect on the various hollow fibers for artificial kidney has been carried out. That is, it was observed that the scavenging effect against radicals generated from redox catalyt on the hollow fibers was able to estimate by the absorbance changes at λ max, at 250nm of UV spectra of ascorbic acid used as the indicater. The order of radical scavenging effect of hollow fibers is as follow. EVAL≥CE ·VE>CE>PSU≥CEt-Ac. It is guessed that the radical scavenging effect of hollow fibrers depends on the chemical structure of the fibers.
