铅是一种广泛存在于自然界中的重金属元素,石墨炉原子吸收法测定水中的铅主要在灰化温度、原子化温度和基体改进剂这三个方面分别进行了比较,找出了最佳的条件,并且在精密度和加标回收率方面也取得了比较满意的结果。
Lead is a kind of heavy metal element widely found in nature. Graphite furnace atomic absorption spectrometry is used to determine lead in water mainly in three aspects: ashing temperature, atomization temperature and matrix improver. The best Conditions, and in the precision and spike recovery also made more satisfactory results.
