An ICP-AES method with standard addition calibration was applied to the determination of micro- amounts of hafnium in Zr-U alloy.
应用电感耦合等离子体原子发射光谱法(ICP-AES),采用标准加入法对锆铀合金中微量铪进行了测定。
The U-Nb-Zr alloy sample is dissolved by HNO3 ,H2O2 and HF, and the contents of Nb and Zr in the sample are determined on the JY-70 n type ICP-AES by using the internal standard synchronous dilution method.
将铀铌锆合金试样用硝酸、过氧化氢和氢氟酸溶解,在JY-70Ⅱ改进型光电直读光谱仪上,用内标同步稀释法,快速、简便地测定了铀铌锆合金中的铌、锆含量。
