电感耦合等离子体原子发射光谱法测定锆铀合金中微量铪
ICP-AES Determination of Microamounts of Hafnium in Zr-U Alloy with Standard Addition Calibration
摘 要
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.当锆的共存量为8 g·L-1时,铪的测定范围是50~400 μg·g-1.在Zr-U合金的基础上分别加入铪50 μg·g-1及400 μg·g-1作回收试验,测得回收率依次为106%及101%,相应的相对标准偏差为5.8%和3.7%.

Abstract
An ICP-AES method with standard addition calibration was applied to the determination of micro-amounts of hafnium in Zr-U alloy.Hafnium was determined in the concentration range of 50-400 μg·g-1 in the presence of 8 g·L-1 of zirconium.Under this condition,tests for recovery were made by addition of 50 μg·g-1 and 400 μg·g-1 of hafnium to a Zr-U alloy,and values of recovery obtained were 106% and 101%,and values of RSD′s (n=6) found were 5.8% and 3.7% respectively.
