Study of electrokinetic properties of regular multimolecular sorbent based on trivalent metals stearates

By the methods of streaming potential and microelectrophoresis electrokinetic properties of regular multimolecular sorbents based on metallic stearates were investigated. It was shown that for two different types of objects such as Langmuir—Blodgett films transferred onto a solid substrate and collapsed monolayers, dependences of the electrokinetic potential on pH of the electrolyte solution are practically identical, which makes the collapsed monolayers of regular multimolecular structures similar to Langmuir—Blodgett films. The values of the isoelectric point for a number of trivalent metal stearates were determined. Basing on these dependences conditions of metal-affinity chromatography sorbents on regular multimolecular were proposed.
