摘　　要：The influence of the concentration of sodium oleate （NaOL） and pentanol on the water uptake of microemulsion was stuied. The effect of the concentraction of NaOL and pentanol on the extraction yield of samarium was investigated. The result shows that the extraction and concentration of samarium is effective under well-defined conditions utilizing Winsor Ⅱ microemulsioin systems. The FT-IR spectra and conductivity research may indicate that stable hydrophobic chelate complexes were produced after the extraction of Sm（Ⅲ） by NaOL micromulsion systems.
