Abstract
A novel polymer for immobilizing precious and heavy metal ions, which have an affinity to sulfur that is in the chemical form of thioether, is described in this application. Metal ions such as Ag(I) which are known to pre precipitate in the presence of salts are stable once bound to the polymer even in the presence of sodium chloride and phosphate salts. The metal ions bound to the polymer retain the ability to interact with chemicals and proteins and can be used to remove or purify them from solution. Because of the affinity of precious and heavy metal ions to sulfur, the polymer could also be used to selectiively recover or remove these metal ions from solution.
