For a project, I need to create an experiment where I remove a heavy metal from water, in my case, iron. I've been doing a lot of searching online so far, and most of what I have found does not relate. I need something that I can actually perform myself, preferably something that I can make on my own.
I heard something about using chlorine to make the iron turn to a less soluble form, and then filtering it but I dont know how exactly to do that.
I just don't know where to start on that idea though. Would I need to acquire some type of Iron, and then get some chlorine? Just let them react in water and filter it? What would I use as a filter? We have filter paper in our classroom but I don't think that'd do it.
