OSMOTIC FLOW IN A RIGID POROUS MEMBRANE

A MAURO. Science. .

Abstract

The concept of an internal pressure gradient in a rigid porous membrane has been proposed as the basis for osmotic flow. The origin of the pressure in terms of the theory of the chemical potential implies also the existence of states of negative pressure, that is, tension. These states have been observed experimentally by means of a Hepp-type osmometer.
