| 摘 要： | 采用微波消解、电感耦合等离子体质谱法（ICP—MS）测定婴幼儿奶粉中的铅元素，并与国标法石墨炉原子吸收光谱法（GFAAS）进行了比较。结果表明：两种方法的测定结果基本吻合，用ICP—MS测定婴幼儿奶粉中痕量铅线性范围宽，抗干扰能力强，测定周期短，完全满足分析的要求，且操作简便快速，应用于实际样品的测定，结果满意。

| Abstract: | Determination of lead element in infant milk powder was done by microwave digestion and inductively coupled plasma mass spectrometry(ICP-MS),and compared with national standard method by graphite furnace atomic absorption spectrometry(GFAAS).Results indicate that the application of two methods for the determination has the roughly same result.ICP-MS determination is of wide linear range,strong anti-interference ability,and short time.It can fully meet the requirements of analysis and has good result when applied to the actual determination of the sample. |
