| Abstract: | This paper deals with the properties of the cellulosic superabsorbent prepared from carboxymethyl cellulose crosslinked with N-methylol acrylamide. The effects of crosslinking conditions on the absorbency of the products was dicussed. The superab-sorbent has been applied in the concentrating of protein solution, the concentrating ability is 2.9 to 3.7 times in 6 hours as normal. If the concentrate operation is repeated once in sequence, it could achieve about 5.6 times in 4 hours. |
