摘　　要：对于加压氧化钼精矿浸出液,通过调节pH,采用电感耦合等离子原子发射光谱法测定铼的含量,通过筛选分析谱线、合理设置背景扣除位置,避免了光谱干扰。方法检出限为0.05-30μg/mL,回收率为95%-100%,RSD小于2.0%,具有良好的精确度和准确度,能够满足日常铼的分析。After adjusted pH without sample pretreatment, a method of inductively coupled plasma atomic emission spectrometry （ICP-AES） was used to analyze rhenium in leaching solution of molybdenum oxide under pressure. The spectral interference was avoided by selecting analytical lines and properly setting background deduction position. The detection limits of method were 0. 05 - 30 μg/mL, and recoveries were between 95 % and 100% and relative standard deviations were below 2. 0%. The accuracy and precision of the method are good.
