采用微波消解法处理八角样品、石墨炉原子吸收光谱法测定八角中铅的含量。此方法的线性范围为0~100.0 ng·mL-1（R=0.9993），加标回收率为95.24%~103.08%，相对标准偏差（RSD）为0.79%~2.61%（n=6）。该方法取样量少、准确度和精密度高，可作为检测八角中铅含量的方法，为食品安全提供可靠的测定技术保障。
採用微波消解法處理八角樣品、石墨爐原子吸收光譜法測定八角中鉛的含量。此方法的線性範圍為0~100.0 ng·mL-1（R=0.9993），加標迴收率為95.24%~103.08%，相對標準偏差（RSD）為0.79%~2.61%（n=6）。該方法取樣量少、準確度和精密度高，可作為檢測八角中鉛含量的方法，為食品安全提供可靠的測定技術保障。

Anise samples were dealt with microwave digestion,then the content of plumbum was determined by graphite furnace-atomic absorption spectrometry. The linear range of plumbum's absorption spectrometry was 0~100.0 ng·mL-1 (R=0.999 3). The adding standard recovery was 95.24%~103.08%. The RSD was 0.79%~2.61%(n=6). This method in which sampling quantity was little, with high accuracy and precision, could be used for detection of plumbum in anise and provided reliable technical support for food safety.
