The adsorption excretion of Hg, As, and Cu ions from aqueous solutions at 22±0.5°C on zeolite (Sokirnitskoe deposit, Transcarpathia) and smectite clay (Kamalinskoye deposit, Krasnoyarsk region) were studied. The adsorption processes were studied in the static regime at pHμ2. Parameters such as, the time of equilibrium establishment, the ratio "sorbent -solution" were selected experimentally. All samples were filtered through a 0.2 μm membrane using syringes. The samples for Hg were selected strictly in teflon dishes and analyzed on the same day by "cold vapor" atomic absorption spectrometry using Portable Mercury Analizer PMA-1 (EcON, Moscow) with a PAR-3m attachment, samples for Cu and As were analyzed by AAC and ICP-MS on ContrAA700 devices (Analytik Jena, Germany) and Element2 (Thermo Scientific, Germany).
