The Peculiarities of Interactions in the System Containing Polyethyleneimine and Unithiol

Interaction processes of polyethyleneimine (PEI) with unithiol were investigated by potentiometric, conductometric and viscosimetric methods. It was stated that in the PEI-unithiol system a complex acidbasic interaction resulted in the formation of salt complex of 2:1 composition. On the basis of experimental data it was stated that complex PEI-unithiol is perspective as a polyadsorbent for many metal ions.
