Abstract

A structural model of precipitation membranes proposed by Hirsch-Ayalon (see [4]) is tested by the following experiments: (a) Measurements of the zeta potential of suspended BaSO4 crystals are used to estimate the sign and the absolute value of the charge density of the adsorption charges of the crystals forming the membrane, (b) the concentration limits for maintaining the membrane properties of BaSO4 precipitation zones, as well as for generating precipitation zones with membrane properties are established. Measurements of the non-ohmic current-voltage characteristics of a BaSO4 precipitation membrane demonstrate that Ba++ ions can be partially replaced by La+++ ions to maintain the membrane properties of BaSO4 precipitation zones.
