- Abstract
The influence of modification of a fumed silica by polyvinylpyrrolidone (PVP) and bovine serum albumin (BSA) on its ability to adsorb iodine has been investigated by UV spectroscopy. It has been established that the adsorption of iodine molecules on the silica surface is increased several times after its modification by high‐molecular compounds. The role of structural factors in complexing of iodine with macromolecules has been estimated. Using PVP and BSA as an example, it is shown that the structure of a modifying layer on the silica surface depends on the nature and structure of the polymer.
