| 中文摘要: |
| 通过硫酸亚铁电位滴定法测定AuBe1、AuNi9、AuAgCu35-5、PdAgCuAuPtZn30-14-10-10-1合金中Au的实践，分析了测定不同Au含量过程中的不确定度来源，建立了数学模型，计算了各标准不确定度分量、合成标准不确定度和扩展不确定度。结果表明：测定合金样品中9.99%、60.16%、90.85%、98.93%的Au含量，扩展不确定度分别为0.02%、0.14%、0.22%、0.24%。 |
| 英文摘要: |
| The uncertainty for potentiometric titration of gold in AuBe1, AuNi9, AuAgCu35-5, PdAgCu- AuPtZn30-14-10-10-1 alloys using ferrous sulfate was evaluated. The sources of uncertainty in the process of determination of gold contents were analyzed, and the mathematical model was established also. The components of standard uncertainty, combined standard uncertainty and expanded uncertainty were calculated. Results indicated that the expanded uncertainties are 0.02%, 0.14%, 0.22% and 0.24% for gold contents of 9.99%, 60.16%, 90.85% and 98.93% in alloy samples, respectively. |
