Need help with a project involving heavy metals

  1. May 11, 2008 #1
    Edit: Just realized that maybe I should have posted this in a different forum... sorry about that.

    Basically my project is to present a method of removing Fe, Mn, Ca or Mg from water and then do an experiment on a sample of water with the heavy metal in it.

    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 could possibly compare different types of products, but there is a $15 spending limit imposed by my teacher.)

    I saw a thread and it looked like removing Iron would be something I could do in an experiment.

    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.

    Please tell me if this would be a feasible option for this presentation/experiment...

    P.S. Here is the thread I saw: physicsforums.com/showthread.php?t=201728

    Search for information and resources about Ion Exchange Resins. That $15 limit will not work.

    Does it have to be just one? Or can you remove them all?

    Because for $15, distillation is in your price range.

    If it has to be just one, here's a page on how they remove iron from well water ...
    but again, seems like just boil and condense the water'll do the trick.

    Some kitty litters (unscented) contain zeolites. Don't use clumping litters. Oil sorbents also contain zeolites. You can get those at some auto parts stores. You might try to activate some with brine, rinse and then pass your sample solution through a bed of the stuff.... slowly! Think tall, thin columns... Demonstration of low cost ion exchange.

    Mr. V, Chemistree, you guys are aware of practical things. Great.
