主　　题：Bismuth(III) Aminododecyldimethylenediphosphonic Acid Solvent Extraction 

摘      要：The extraction of Bi(III) in nitrate media has been investigated using aminododecyldimethylenediphosphonic acid, ADDMDPA, which was previously synthesized and characterized. The extraction of the cation was carried out in different media with the addition of CH3COONa, KNO3 and HNO3. The maximum extraction yield for Bismuth is 70% after addition of 0.01 M of potassium nitrate at pHi = 2.9, in one step.
