Abstract
The invention provides polymeric matrices and films comprising fixation reagents that are capable of reacting with solubilized metals to form less soluble metal compounds. The fixation reagenst may include inorganic sulfides and phosphates, as well as adsorbents. The polymeric matrices may be comprised of polyvinyl alcohols and polyvinyl acetates. In some embodiments, the polymeric matrix is selected to be at least as soluble as the selected fixation reagent, particularly under the conditions in which the matrix is expected to come into contact with the solublized metal.
