With regard to the harmful effects of heavy metals on human health and the environment, the demand for synthesis and investigation of macromolecules with large capacity of harmful substances sorption is ever greater. Quantum-chemical methods may be applied in structural modeling, prediction, and characterization of such molecules and reactions. Sorption of metal ions (Cu2+, Cd2+, Co2+, and Ni2+) to triethylenetetramine-functionalized copolymer poly(GMA-co-EGDMA)-teta was successfully modeled by quantum chemical calculations, at the B3LYP//6-311++G**/lanl2dz level. Optimized structures of metal complexes were used for calculation of real binding energy of metal ion within the complex (Er). Solvent and hydrolyzation effects were essential for obtaining the objective values. Solvent effect was included in Er by using the total solvation energy for reaction of formation of tetaOH complex (Es1, the first approach) or by using dehydration energy of free metal ion (Es2, the second approach). ...Experimental results were confirmed in our theoretical analyses (using the second approach).
