Cu是用原子吸收法测定的常见元素之一,然而高含量Cu的测定还不多见。本文用火焰原子吸收法对铜合金中高含量Cu的测定进行了较系统的研究并建立了测定方法。用含Cu量为58.85～95.39％的八种铜合金材料标样进行校验,测定值与标准值相符,相对标准偏差均在0.3、0.4％。 本法准确、快速、重现性好,共存元素无干扰。 Cu is one of the common elements measured by atomic absorption spectrometry, however, the determination of high Cu content is rare. In this paper, flame atomic absorption spectrometry for the determination of high Cu content in copper alloys was systematically studied and the determination method was established. Eight kinds of copper alloy samples with Cu content of 58.85-95.39% were used for calibration. The measured values ​​were consistent with the standard values, with relative standard deviations of 0.3 and 0.4%. This law is accurate, fast, reproducible, co-existence of elements without interference.
