【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,已成功应用于碳纳米管中负载Pt的快速检测。更多还原

【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.更多还原
