中文摘要: 采用高压水热釜处理后，利用电感耦合等离子体原子发射光谱(ICP-AES)法测定碳纳米管中负载的铂。对仪器参数以及被测元素的谱线选择进行了讨论。在选定最佳条件下，探讨了检测方法中检出限、精密度及加标回收率等指标，方法相对标准偏差小于5%(n=5)，加标回收率为 101%～114%。方法实用性强，可成功应用于碳纳米管中负载的Pt的快速检测。
Abstract:The loading amount of Pt on carbon nanotubes (CNTs) was determined by inductively-coupled plasma atomic emission spectrometry (ICP-AES) after the acid-treatment process in an autoclave. The instrument parameters and the analytical lines of Pt were discussed. The Pt concentration was determined at the optimum conditions. The relative standard deviation (RSD) was less than 5% (n=5) and the recoveries were in the range of 101 % ～ 113 %. This method is practical and can be successfully applied to the detection of Pt on carbon nanotubes.
