| 中文摘要: |
| 采用焚烧、球磨混合、研磨取样等工序，对含铂族金属炭载体失效催化剂的取样、制样研究，获得的分析样品对失效催化剂的物料具有较好的代表性。经4批不同含量的失效含铂族金属炭载体催化剂取样测定，相对标准偏差(RSD, n=5)在0.19%~0.28%之间。 |
| 英文摘要: |
| The sample and sample preparation of platinum-containing metal carbon carrier failure catalyst were studied by using incineration, ball milling, grinding and sampling. The obtained sample was better representative of the material of the failure catalyst. Platinum group metal catalyst on carbon carrier was sampled for failure of batches containing various amounts of 4,the relative standard deviations (RSD, n=5)were between 0.19% and 0.28%. |
