Characterization and Atomic Simulation of Selenium Nanoparticles Stabilized with Sodium Lauryl Sulfate (SLS)

This paper presents the results of studying selenium nanoparticles stabilized with sodium lauryl sulfate (SLS). Selenium nanoparticles are obtained by chemical reduction in an aqueous medium. It is shown that the optimal parameters for the synthesis of nanoparticles are selenium, the concentration of selenous acid is 0.04 M, the concentration of sodium lauryl sulfate is 0.1 M, and the concentration of ascorbic acid is 0.75 M. Investigation of the effect of the medium active acidity showed that obtained selenium nanoparticles exhibit aggregation stability at a pH from 2 to 8. The analysis of a different reaction to the aggregation of the occurrence of selenium nanoparticles reveals a significant effect on the particle size of metal cations, accompanied by particle aggregation.
