| Abstract: | In this paper, we have studied the meassuring condition and the extracting condition for the determination of trace copper and lead in highly pure samaria by extraction-GFAAS. Trace copper and lead in highly pure samaria were determined. The relative standard deviations are less than 6%, the recovery is 98-101% for copper and 93-100% for lead. The method is simple, accurate and practical. |
