摘要
本文采用液相还原法以硼氢化钠作为还原剂,在十二烷基硫酸钠保护下合成了采用一次还原、二次还原制备不同粒径的纳米银,用傅立叶红外光谱(FTIR)、紫外-可见分光光度计(UV-vis)、荧光分光度计等对纳米银的进行了表征。结果表明:纳米粒子稳定,且二次还原粒径明显长大。
Sliver nanopartieles with protecting of PVP by were prepared by chemical reduction. And the size and stabilization of nanoslive were characterized by Uv - vis,FTIR. The results showed that the mean diameter of the nanoparticles in secondary reduction was larger and nanopartieles has the strong sterilization.
