摘要
建立了锌阳极中铝的测定方法,试样用1∶1 HNO_3溶解后,以石墨炉原子吸收光谱法测定,研究表明:以抗坏血酸作基体改进剂,可直接用标准溶液校准,测定锌阳极中的铝,且原子化温度降低,灵敏度、准确度提高。本文还对最佳测量条件及原子化机理进行了研究和讨论。方法简单、快速,测定结果令人满意。
Aluminum in zinc anode is determined by graphite furnace atomic absorption spectroscopy. It was shown that ascorbic acid is a good matrix modifier, and the mechanism is discussed in detail. The method presented is simple and rapid.
