Figure 2From: Coordinative interaction of microcrystalline chitosan with oxovanadium (IV) ions in aqueous solutionTitration of the H+- VO(IV) - MCCh (DD = 0.977) system at various ligand to metal ratio. CMCCh (mol L-1) = 7.0 × 10-3. The value of base equivalent a = 0.1 corresponds to HNO3 in excess as related to ligand.Back to article page
