Complexation of vanadium(V) oxoanion with ethanolamine derivatives in solution and in a cross-linked polymer

Vanadate reacts with the functional group of ECTEOLA-Cellulose to form the −1 charged 1:1 (N,O,O)-tridentate complex. In addition to the anion exchange interaction of monovanadates and isopolyvanadates with the protonated functional group, in the alkaline region the adsorbability of vanadium(V) onto ECTEOLA-Cellulose is a consequence of the complexation with the functional group.
