Abstract
The effects of annealing temperature on the mechanical properties and the desalination performance of cellulose acetate membranes have been investigated. A critical temperature Tc exists at which all membrane properties change abruptly. In addition, the effects of low concentrations (10−4-10−1 mol/l) of phenol in the solution on the mechanical properties and on the water content of the membranes have been established. At the same concentration at which the phenol uptake sharply increases, a significant decline of water content and mechanical properties have been found.

The results confirm close relationships between the physical properties and the desalination performance.
