Extraction chromatography is being considered as a nondestructive method of material accountancy of spent nuclear fuel for safeguarding purposes. By analyzing the amounts of Am, Cm, and Pu, the quantity of other elements created during the fuel cycle can be determined using known ratios of spent fuel. DGA has a high affinity for Am, Cm, and Pu in HCl and HNO3 and is being studied for sorption characteristics. Since DGA extracts neutral species, the anion in the system has the potential to lead to deviations from normal actinide sorption in HCl and HNO3.  In order to determine the effect of anions on actinide sorption, batch contact studies were performed and analyzed using LSC and ICP-AES. SO42-, Br-, and I- were introduced as anions into HCl and HNO3 matrixes to observe any changes in Am, Cm, Pu k' values. Upon analysis, the anions showed varying interference and synergistic trends on actinide sorption.
