Synthesis of Selenium-Containing Humic Nano-Biocomposites from Sodium Bis(2-phenylethyl)phosphinodiselenoate

摘要

New water-soluble selenium-containing nano-biocomposites have been synthesized by oxidation of sodium bis(2-phenylethyl)phosphinodiselenoate with hydrogen peroxide using humic substances to stabilize selenium nanoparticles. As shown by a set of physicochemical methods, the obtained hybrid nanocomposites are formed as spherical hexagonal selenium particles with a size of 13-30 nm, dispersed in a humic matrix.
