Abstract

The purpose of the invention is a method and an apparatus for determination of the flow potential of an aqueous solution. In a method according to the invention, the aqueous solution being investigated is moved under pressure from a container 7 via a pipe 9 across a flow constriction 1, 5 and via a different pipe 10 to another container 8, where the prevailing pressure is lower than in the first container 7, and the potential difference of the flowing solution and the nonflowing solution is measured with electrodes 2, 6. The apparatus according to the invention includes containers 7, 8, pipes 9, 10 connecting the containers, a flow constriction 1, 5 located between the pipes, through which the aqueous solution is arranged to move from the one container 7 to the other container 8, the electrodes 2, 6 measuring the flow potential of the solution during the movement, and a potentiometer 16, which measures the potential difference between the electrodes 2, 6. <IMAGE>
