本文介绍应用灵敏显色剂5-Br-PADAP在环炉上进行多种金属离子测定的试验,并对测定Fe(Ⅱ)的显色条件,消除干扰离子的方法及其最佳测定范围进行了初步研究。本方法可用于镀锌废水中微量铁的测定。
This article describes the application of a sensitive reagent 5-Br-PADAP in a ring furnace for a variety of metal ions in the determination of the test, and determination of Fe (Ⅱ) color conditions, the method to eliminate interference ions and its best determination of the range initial research. The method can be used for the determination of trace iron in galvanized wastewater.
