Separation of phosphates, nitrates and nitrites

  1. Jan 17, 2009 #1

    If you had an aqueous solution of phosphates, nitrates and nitrites, how could you separate them?

    Also, if not answered above, how could you separate a solution of just nitrates and nitrites?

    thank-you for you're time

    That will depend on many factors. Do you want to separate them for analysis? Or in some industrial process? What are cations present?

    I would first precipitate the phosphates with CaCl2 or BaCl2, for example; then I would precipitate the nitrites with, e.g. AgF.
