Abstract

Chelation of Nd3+ 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 Nd3+ species at elevated pH.
