摘要/Abstract

摘要：

探讨了硝酸铅和金属铅作为对照品测定铅含量的方法。结果表明,二者铅的测定值没有明显差异(P≥0.05),硝酸铅溶液比金属铅溶液相对稳定,因此,以硝酸铅代替金属铅作为对照品,操作简便、使用安全,具有较强的实际应用价值。

Abstract:

Method of lead determination using lead nitrate and metallic lead as reference substances was discussed in this paper. The results showed that there was no significant difference between lead nitrate and metallic lead(P≥005). Meanwhile, solution of lead nitrate was more stable than metallic lead. It is simple and safe to use lead nitrate instead of metallic lead as reference substance. This method has strong practical application value.

Key words: atomic absorption spectrometry, lead nitrate, metal lead
