摘要
在EDTA(乙二胺四乙酸 )化学清洗过程中 ,铁含量的测定是不可缺少的 .根据《清洗导则》中的方法进行现场测试 ,常常会发生含铁量结果明显偏低的情况 .详细阐述了通过试验提出这一问题的过程 ,并定性地摸索出加入三乙醇胺络合铁离子这一适应现场条件、方便快捷的测定方法 .
In the process of EDTA chemical cleaning, it is indispensable to measure the ferric concentration. According to the method of cleaning instruction we measure on the spot, the content of iron is often obviously low. The problem set forth by the experiment is expatiated carefully, a measure method is fished out of addition of (HOCH 2CH 2) 3N-Fe, a condition adaptive to the spot.
