title: MERCURY (II) ADSORPTION ON MINERALS OF MAIKOP SERIES ROCKSAND MUD VOLCANO CLAYS
abstract: The acid-base properties of the surface of the Maikop series clays and mud volcano clays, as well as their adsorption properties with respect to mercury (II) ions, were studied. It is shown that pH PZC for the former is 7.1 on average; for the second — 9.0. The pH PZC value for mud volcano clays is consistent with the pH values in the waters of mud volcanoes in the Kerch-Taman region. When the mass ratio of the sorbent and solution is 1:900, adsorption equilibrium occurs after 4 days with active
