测定窖泥和黄泥金属元素的不同前处理方法对比分析

Comparative Analysis of Different Pretreatment Methods for the Determination of Metallic Elements in Pits Mud and in Yellow Mud

对测定窖泥和黄泥中金属元素的3种前处理方法进行了比较。结果表明,有机酸法测定结果较低,无机酸法测定结果居中,消解法测定结果最高;对窖泥和窖泥用黄泥,用有机酸法前处理测定金属元素含量更能反映窖内的真实情况。

In this study, three different pretreatment methods for the determination of metallic elements in pit mud and in yellow mud were compared. The determination results with organic acids method were the lowest, the determination results with inorganic acid method were high, and the determination results with digestion method were the highest. Accordingly, the determination with organic acids method could reflect metallic elements content in pits more realistically.
