| 中文摘要: |
| 采用硝酸溶解四(三苯基膦)钯样品，高氯酸发烟分解有机物，以络合滴定法测定钯含量。对样品发烟分解条件进行了详细考察，结果表明，高氯酸残留量在1.0 mL以内，经3次发烟可完全分解有机物。采用丁二肟析出-EDTA络合滴定法测定钯，所得结果相对标准偏差(RSD)为0.28%，加标回收率为99.66%~100.04%，满足样品中钯含量测定的要求。 |
| 英文摘要: |
| : Samples were digestion by HNO3-HClO4 , then dissolved with HNO3-HCl. Using EDTA complexometric, ZnNO3 back titration by dioxime precipitation determinated palladium content in samples. The method discussed conditions of digestion by HNO3-HClO4. The results showed that the residual amount of HClO4 was within 1.0 mL, and the organic matter was decomposed completely by 3 times of smoke. The standard recovery rate was 99.66%~100.04%, and the relative standard deviation (RSD) was 0.28%. These results meet the requirements of determination palladium. |
