| 中文摘要: |
| 试样采用HNO3-HClO4湿法消解、或在700℃下灼烧除去碳，王水溶解残渣后用ICP-AES测定钯含量。考察了样品前处理、方法精密度和准确度，样品加标回收率为99%~101%，相对标准偏差<1%。方法准确、快速、简便。 |
| 英文摘要: |
| The content of Pd was determined through (1) wet digestion with HNO3-HClO4 or ignition at 700℃ to remove carbon, (2) dissolution of the residues by aqua regia and (3) determination of palladium by ICP-AES. Pretreatment of sample, accuracy and precision of the method were discussed. The additional standard recovery is 99%~101%, RSD <1%. The method is simple, accurate and fast. |
