The possibility of extraction of iron cations Fe2+ from the wash plant electroplating wastewater by carbon sorbents IPI-T synthesized in ISTU has been stated in this work. In this paper we studied the regularities of sorption in static and dynamic conditions, the numerical values defined limiting sorption of iron cations Fe2+ in the interval of temperatures 293-313 K. Such thermodynamic parameters of sorption as Gibbs free energy and enthalpy and entropy changes have been calculated.
