title: Neodymium(III) complexation by amino-carbohydrates via a ligand-controlled hydrolysis mechanism.
abstract: Chelation of Nd(3+) by D-glucosamine (DGA) and chitosan was investigated in solution at near-physiological pH and ionic strength. This research demonstrates the first example of the lanthanide ion heteroleptic hydroxo-carbohydrate complex in solution. Amino-carbohydrates DGA and chitosan suppressed formation of polynuclear Nd(3+) species at elevated pH.
