中文摘要:

      采用硝酸-氢氟酸-高氯酸消解样品,电感耦合等离子体发射光谱法测定地质样品中的钨. 讨论了Zn207.908对W 07.911的光谱干扰,并应用光谱干扰系数校正法(IEC)校正干扰. 结果表明:Zn对W的光谱干扰可以用IEC进行有效的消除,进行光谱校正后的结果明显优于未加校正的试验结果.

英文摘要:

      A method for the determination of W in geological samples by inductively coupled plasma-atomic emission spectrometry(ICP-AES) has been developed. The sample was decomposed by HNO₃-HF-HClO₄. The spectral interference of Zn 207.908 to W 207.911 was discussed,and the interference can be corrected using the interference correction method (IEC).The results showed that the spectral interference of Zn to W can be thus effectively eliminated,the results after the spectral correction were evidently better than the results without the spectral interference correction by the IEC.
