Abstract
The complex ion [Cu(NH3)4]2+ was quantitatively retained by spruce woo d bark chemically modified in the presence of formaldehyde and acid me dia (nitric or sulfuric acid). The concentration of the above-mentione d ion was a result of the ionic exchange, an essential role being also played by the chemical components from wood bark, and by the transfor mations produced by chemical treatments, as well. Spectral and thermog ravimetric investigations offered information on both complex ion bond ing and stability of formed bonds.
