巯基棉分离富集-FAAS法测定爆玉米花中痕量铅

Determination of Trace Lead in Pop Corn by Separating and Enriching with Sulfhydryl Cotton and FAAS

本文借助巯基棉分离富集技术，以火焰原子吸收光谱法（ＦＡＡＳ）测定爆玉米花中痕量铅。该方法采用巯基棉做分离富集剂，简便易行，并能有效的消除共存元素的干扰，回收率为９７．５％ —１０６．０％ 。

The determination of trace lead in pop corn after separating and enriching with sulfhydryl cotton by FAAS is described in this paper.The characteristics of this method is fast,simple and convenient.Sulfhydryl cotton is effective in eliminating of interference for common existing elements.The recovery of lead is 97.5%—106.0%.
