| 中文摘要: |
| 采用火试金重量法测量含金碳基催化剂中金含量，通过焙烧温度、称样量、物料配比、金银质量比以及分金酸度等确定最优实验条件。在最优实验条件下通过加标实验，标准物质回收率99.0%~100.6%。方法准确度良好，可运用于实际生产分析。 |
| 英文摘要: |
| The gold content in gold-containing carbon-based catalyst was measured by fire gold gravimetric method, and the optimal experimental conditions were determined by roasting temperature, sample weight, material ratio, gold/silver mass ratio and gold separation acidity. Under the optimal experimental conditions, the recovery rate of standard substance was 99.0%~100.6%. The method has good accuracy and can be used in actual production analysis. |
