摘要： 采用水(溶液)/Triton X-100/环已烷/正戊醇反相微乳体系，制备出了粒径分布均匀、尺寸在10~30 nm范围内的CaCO3纳米颗粒. 对不同w0、反应物浓度、陈化时间等因素的影响进行了研究，获得了最佳的反应条件. 所得产物利用透射电子显微镜分析进行了表征.

关键词: W/O微乳液, CaCO3, 纳米颗粒

Abstract: CaCO3 uniform nanoparticles with particle size of 10~30 nm were synthesized in quaternary W/O microemulsion solution containing Triton X-100, cyclohexane and n-pentanol. The reaction conditions were optimized on the basis of investigation of the influence of the ratio of water to surfactant, the concentration of reactants and the ageing time on the products. Transmission electron microscopy (TEM) was utilized to characterize the shape and size of the obtained nanoparticle products.

Key words: He-Ne laser, Beauveria bassiana, mutagenesis
