| 中文摘要: |
| 采用硝酸-高氯酸分解试样，ICP-AES法同时测定铅、铜和铁。建立了一个准确、快速、简便的测定方法，适用于新制和失效钯炭中铅、铜和铁量的测定。Pb、Cu、Fe测定范围为0.01%~0.1%；方法的加标回收率为95.8%~100.9%；相对标准偏差RSD<5%。 |
| 英文摘要: |
| A simple accurate and precise analytical method for the determination of lead, copper and iron in palladium-carbon catalysts by ICP-AES was proposed. The digestion of sample which contains lead, copper and iron in the range between 0.01%~0.1% in fresh or spent palladium-carbon, was obtained using both HNO3 and HClO4. The recoveries were ranged from 95.8% to 100.9%. The precision, expressed as relative standard deviation (RSD) of the method, is better than 5%. |
