Abstract

Initial decrease of electrokinetic potential followed by certain increase of the latter as a result of long-continued refining and subsequent fractioning under the different of membrane packing and electrolyte concentration has  found.  The dependence of the electrokinetic potential from the average fiber length was found. It was shown that  fibers longer length, have  the higher the electro kinetic potential. Reduction of carboxyl groups  content during refining and fractioning of wood pulp and a slight increasing its in the fraction  of 200 mesh cotton pulp was found. Author's vision of the possible structure of the electric double layer on the pulp fibers has   presented.
