| Abstrakt: |
The permeability of standard Soviet ultrafiltration membranes prepared from cellulose acetates was investigated with respect to biologically active substances (hemoglobin, trypsin, ribonuclease, vitamin B12, hydroxytetracycline) and inorganic salt (KH2PO4). The arrest of a substance by a membrane of a certain structure depended primarily on the size of the substance macromolecule in the solution. The filtration rate was related to the membrane type, pressure gradient and composition of the filtered solution. Potential use of the tested membranes is described. |
