CHEMICAL MODIFICATION OF THE SURFACE OF THE POLYETHYLENE TEREPHTHALATE PET AND ITS APPLICATION THEREOF FOR REMOVING WATER DISSOLVED METALS.

摘要

The present invention refers to the chemical modification of the PET surface and its application as a novel adsorbent material for removing metallic ions such as iron, manganese, copper, lead, thallium, cobalt, mercury, chromium, nickel, vanadium, selenium, zinc, tin, cadmium, antimonium, selenium and further chemical species such as cyanide and fluoride from aqueous solutions by means of a balance technique per batches. The PET was obtained from carbonated beverages; it was subjected to crush and to a chemical treatment with methionine.
