Abstract

Abstract: The effect of sucrose on nanometer Se⁰ in liquid phase was reported. Transmission electron microscope(TEM), laser light scattering image and Resonance Rayleigh Scattering(RRS) were used to study the configuration and stability of nanometer Se⁰ particles. The results show that sucrose solution modulated the assemble of nanometer Se⁰ particles and stabilized the Se⁰ particles in liquid phase. From the concentration of 1.07 to 42.8 μmol/L, the diameter of Se⁰ particles were 47—600 nm. However, in the presence of 1.0% sucrose solution, the major distribution range of Se⁰ diameter was 20—80 nm. Furthermore, the nanometer Se⁰ sol-gel could be preserved stably in sucrose solution at least for 2 months at 2—10 ℃.

Key words: Nanometer Se⁰ particle, Sucrose, Assemble, Modulation
