| 中文摘要: |
| 研究了Ru/Al2O3催化剂中钌含量的测定，考察了溶样方法、测定方法、测定条件的影响。选用750℃过氧化钠熔融，以高锰酸钾和铋酸钠蒸馏分离，用电感耦合等离子体原子发射光谱法(ICP-AES)测定样品中钌含量。结果表明，方法测定含量范围0.1%~10%，精密度(RSD)为2.0%~2.5%，加标回收率为96.9% ~102.8%，可满足实际物料中钌含量测定的要求。 |
| 英文摘要: |
| The determination of ruthenium content in Ru/Al2O3 catalyst was studied. The sample dissolving, the determination method and conditions were investigated. The sample is melted by sodium bismuthate and sodium peroxide at 750°C. Ru was distilled and separated from the solution. Concentration of Ru was determined by inductively coupled plasma atomic emission spectroscopy (ICP-AES). The determination range is 0.1%~10%, with an RSD of 2.0%~2.5% and recoveries of 96.9~102.8%. The methods can meet the requirement of ruthenium content determination for the real materials. |
