Аннотация: The adsorption properties of sand-gel material (SGM) with respect to mercury (II) ions were studied. It has been shown that studying adsorption under static conditions is incorrect, since upon contact with the sorbent, oxalates pass into the solution, forming stable complexes with mercury that are not capable of sorption. The efficiency of mercury absorption by SGM in the presence of nickel, copper, zinc and lead was assessed. It has been experimentally shown that the adsorption value of mercury on SGM reaches 0.4 mg/g. Metal adsorption decreases in the order Hg > Pb > Cu > Zn > Ni. The absorption capacity of the sorbent for mercury (II) ions is 0.67 mg/cm3. It has been established that the studied material effectively absorbs mercury (II) ions, and therefore can be used for wastewater treatment with mercury contamination.
