| 中文摘要: |
| 对二甲基乙二醛肟析出-EDTA络合滴定法测定系列钯化合物中钯量的不确定度进行了分析与评定，并计算出扩展不确定度。结果表明，测定二氯化钯、醋酸钯、二氯四氨钯、硝酸钯溶液和硫酸钯溶液中59.59%、47.73%、42.46%、17.64%和4.01%的钯含量，扩展不确定度分别为0.30%、0.26%、0.24%、0.10%和0.03%。不确定度主要来源于终点判断和标定过程。 |
| 英文摘要: |
| The uncertainty for complexometric titration of EDTA to determine the palladium contents in palladium compounds was evaluated, and the expanded uncertainties were calculated. Results indicated that the expanded uncertainties are 0.30%, 0.26%, 0.24%, 0.10% and 0.03% for palladium contents of 59.59% (PdCl2), 47.73% (Pd(OAc)2), 42.46% (Pd(NH3)4Cl2), 17.64% (Pd(NO3)2 solution) and 4.01% (PdSO4 solution) in palladium compounds, respectively. The uncertainty mainly came from the end judgment and calibration process. |
