ABSTRACT

High efficiency, degree of cleaning, and renewability of raw materials make the natural polymers a proper material for the control of the content of metals in aqueous solutions, and for their concentration and removal. The greatest interest today represents the application of the modified natural polymers, not only for adsorption and concentration of metal ions, but also for receiving pharmaceutical preparations containing metal nanoclusters, catalysts, and nanoparticles of metals [1-6].
