摘要：
The results of study of the sorption of nickel(II) ions from aqueous solutions by a finely porous carbon adsorbent (CA) and its modified analogs are presented. Organic reagents selective towards nickel(II) are applied as modifying agents. The isotherms of adsorption are obtained in various temperature modes. The thermodynamic parameters of adsorption are calculated. The increase in the limiting sorption capacity values and the sorption equilibrium constants is established for the modified samples in comparison with the initial ones.
