Specific Features of Interaction of Polyacrylic and Polymethacrylic Acids with Nanopartides of Amorphous Selenium

摘要

A study was made of formation of selenium nanopartides in water from reduction of sodium selenite with ascorbic acid in the presence of polyacrylic and polymethacrylic acids.It is well known that nanopartides of zero-valence metals and nonmetals,with their specific structural features and high surface energy,exhibit abnormal physicochemical properties because of the scale effect of matter 1.Of special interest are nanopartides of selenium,a chemical element with unique photoelectric,semiconducting,catalytic,and biological properties and X-ray sensitivity.
