An ultrafiltration unit has been designed, and constructed to contain a 10-ml volume. The unit is leakproof, is self-contained, and can be operated inside a small refrigerator or oven. It has been used with "Visking" cellulose acetate membrane to separate the colloidal protein phase of human blood serum from the aqueous dispersing phase, and to study the distribution of certain nitrogen mustards between these phases. The results indicate that these drugs are adsorbed to the protein to a high degree and that the presence of the benzene rings in the nitrogen mustards is mainly responsible for this adsorption.

Cellulose Acetate Membranes

Ultrafiltration cellulose acetate membrane can be transformed by annealing into reverse osmosis membranes (RO type). Annealing brings about changes in structural properties of the membranes, accompanied by changes in their permeability behaviour and electrical properties. Correlations between structure parameters and electrochemical properties are shown for the temperature range 20-90 °C. Relations have been derived which explain the role played by the dc electrical conductivity in the characterization of rejection ability of the membranes in the reverse osmosis, i.e. rRO = (1 + exp (A-B))-1, where exp A and exp B are statistically significant correlation functions of electrical conductivity and salt permeation, or of electrical conductivity and water flux through the membrane, respectively.
