The surface of a carbon sorbent modifi ed with poly-N-vinylpyrrolidone was studied by X-ray photoelectron spectroscopy (XPS). The modifi cation involves polymerization of N-vinylpyrrolidone on the carbon sorbent surface to form poly-N-vinylpyrrolidone. The elemental composition of the carbon sorbent surface before and after modifi cation was determined by XPS. The electronic state of atoms of the identifi ed elements on the surface was evaluated. The contact of the modifi ed carbon sorbent with normal saline simulating the biological medium leads to partial removal (desorption) of the polymer from the granulated sample.
