How to quantitatively detect sulfate ions in desulfurization gypsum?
Thread Content
I want to detect sulfate ions in desulfurized gypsum. What are some good chemical analysis methods? Simple instrumental analysis methods will also work; thank you
The detection of sulfate ions can generally be done using complexometric titration, but considering the influence of calcium ions, the gravimetric method is better. Last edited by lifanwang on 2009-4-8 20:14.]
The original poster can refer to this: http://bbs.hcbbs.com/viewthread.php?tid=376822
It can be determined by the barium sulfate gravimetric method. The classic method. The only downside is that it takes a bit longer.
