The effect of sucrose on nanometer Se~(0) 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 Se~(0) particles.The results show that sucrose solution modulated the assemble of nanometer Se~(0) particles and stabilized the Se~(0) particles in liquid phase.From the concentration of 1.07 to 42.8 μmol/L,the diameter of Se~(0) particles were 47—600 nm.However,in the presence of 1.0% sucrose solution,the major distribution range of Se~(0) diameter was 20—80 nm.Furthermore,the nanometer Se~(0) sol-gel could be preserved stably in sucrose solution at least for 2 months at 2—10 ℃.
The effect of sucrose on nanometer Se ~ (0) 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 Se ~ (0) particles. The results show that sucrose solution modulated the assemble of nanometer Se ~ (0) particles and stabilized the Se ~ (0) particles in liquid phase. From the concentration of 1.07 to 42.8 μmol / L, the diameter of Se ~ (0) ) particles were 47-600 nm. However, in the presence of 1.0% sucrose solution, the major distribution range of Se ~ (0) diameter was 20-80 nm. Ferrthermore, the nanometer Se ~ (0) sol-保存 stably in sucrose solution at least for 2 months at 2-10 ℃.
