火焰原子吸收法测定电子焊料中的微量元素

Determineation of Trace Element in Soldering by FAAS

本文采用火焰原子吸收法(FAAS)建立了一种简便、快速、准确的测定电子焊料中铁、铜、锌、镍、银、铝、镉等微量元素的检测方法。采用该方法配制的溶液可同时对多种杂质元素进行检测,且元素之间的干扰少,检测的精度高,具有一定的推广和应用价值。

A simple,quick and precision method of measuring the trace element in soldering is introduced in this article.Based on analyzing the same solution of the soldering,the trace elements （such as Fe,Cu,Zn,Ni,Al,Cd ） can be separately inspected by means of Flame Atomy Absorb Spectrum（ FAAS）.The method had the characteristic of practicality,and can be popularized.
