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 pH?2. Parameters such as, the time of equilibrium establishment, the ratio "sorbent - solution" were selected experimentally. All samples were filtered through a 0.2 ?m membrane using syringes. The samples for Hg were selected strictly in teflon dis...
