摘要
在PCB生产过程中,将会产生许多的工业废水,这些工业废水,可以通过调节PH值,使一些金属离子沉淀,如Cu2+、Al3+、Mn2+、Sn2+等,它们都可以通过调节PCB工业废水的PH值,来达到工业废水的处理。那么,怎样测量工业废水中的PH值呢?
The PCB has producted proess ,There have been mary indusion waste water, these industrial wast water will adjust pH rate to get some medal ions precipitated.For example： Cu^2＋, Al^3＋, Mn^2＋, Sn^2＋ etc.they can go through adjustmen the. pH rat had industral waste water got treatmented, So how has the pH rate measued in the industrial waste water.
