| 中文摘要: |
| 采用水合肼作还原剂，还原后的金属钯黑再通氢还原纯化，建立了水合肼-氢还原重量法测硫酸钯溶液中的钯含量。在优化后的测定条件下，测定了4.00%~14.50%含量的钯，分析结果的极差、相对标准偏差(RSD，n=6)分别为0.02%、0.062%~0.16%。与GB/T 23276-2009法相比较，测定结果的准确度和精密度更高。 |

| Content Using hydrazine hydrate as reducing agent, the reduced palladium black was purified by hydrogen reduction, the determination of palladium in PdSO4 solution by hydrazine hydrate and hydrogen reduction gravimetric method was established. Under the optimized conditions, the palladium content of 4.00%~14.50% was determined. The results showed that the ranges and the relative standard deviations (RSD, n=6) was 0.02%、0.062%~0.16%, respectively. Compared with GB/T 23276-2009 method, the accuracy and precision of this method are higher. |
