摘要
采用电感耦合等离子体原子发射光谱法(ICP-OES)、原子吸收光谱法(AAS)和X射线荧光光谱法(XRF)对铜锌合金、铝合金、铁合金及磁铁中的铅含量进行测试分析,重点探讨ICP-OES测试中铅的波长选择及干扰因素。结果表明:铜锌合金中铅含量宜采用220 nm或283 nm波长测定;铝合金中283 nm和405 nm波长数据可靠性较高;在铁合金中可以使用220 nm处的测试结果;磁铁样品中ICP-OES测试干扰极大,必须依赖AAS进行准确测定。本研究为合金中铅含量的快速筛选与精准检测提供了实验依据。
Inductively coupled plasma optical emission spectroscopy(ICP-OES),atomic absorption spectroscopy(AAS)and X-ray fluorescence spectroscopy(XRF)were used to test and analyze the lead content in copper zinc alloys,aluminum alloys,iron alloys and magnets,focusing on the wavelength selection and interference factors of lead in ICPOES testing.The results indicate that the lead content in copper zinc alloys should be determined using wavelengths of 220 nm or 283 nm.The reliability of 283 nm and 405 nm wavelength data in aluminum alloys was relatively high.Ferroalloys can be determined using wavelengths of 220 nm.Magnetic samples required determination through AAS.This study provided experimental evidence for the rapid screening and precise detection of lead content in alloys.
