摘要
目的采用石墨炉原子吸收法(GFAAS)检测中药材金银花中微量重金属镉的含量。方法考察灰化/原子化温度等因素对测定的影响,建立石墨炉原子吸收光谱法测定金银花中微量镉的方法。结果发现金银花中均检出镉(Cd),其中有3批超出中国药典2010版一部所规定的限度。结论方法简便快速,重复性好,灵敏度、准确度高。
OBJECTIVE The Cd in honeysuckles was determined by graphite furnace atomic absorption spectrometry. METHODS The best conditions were confirmed by the investigation of ashing temperature, atomization temperature. RESULTS Cadmium （Cd） were detected in honeysuckle, three batches of honeysuckles were beyond the limit stipulated in the Chinese pharmacopoeia 2010 edition. CONCLUSION The method is simple, fast, reproducible, high sensitive and accurate.
