| 中文摘要: |
| 为完全分解样品，消除碳的影响，以H2SO4+HNO3冒烟消除碳，甲酸还原，王水溶解，在ICP-AES选定的条件下测定废钯炭催化剂样品中钯的含量。样品加标回收率97.0%~101.6%，测定0.099%~0.324%的钯含量，相对标准偏差2.55%~2.84%，方法与灼烧还原法及火试金法测定结果一致，方法简单快速，环保节约，结果准确。 |
| 英文摘要: |
| In order to decomposes the sample completely and eliminate the impact of carbon, preparation of sample, carbon removed by H2SO4+HNO3 smoking, formic acid reduction, dissolved by aqua regia. determine palladium content in the selected conditions of ICP-AES. The recovery ranged from 97.0% to 101.8%, the relative standard deviation (n=6) is less than 3%, determination result of the method and method of ignition reduction and fire assay is consistent, the method is simple and fast, environmental protection, conservation, and accurate. |
