| 主权项 | 1. A sorbent comprising a microporous material comprising chitosan which has been crosslinked with glutaraldehyde in the presence of a catalyst to a glutaraldehyde concentration of about 2 to about 4 wt %, which is resistant to degradation from exposure to beta and gamma radiation and from exposure to acids, and which has been at least partially oxidized after crosslinking. | ||
