摘要：

Cu2+ transformations of Cu and its oxides particles with different sizes in the simulated uterine solution were investigated by absorbance measurements. The corrosion intermediate of Cu nanoparticle in the simulated uterine solution was determined by using XRD technique. The results show that the transformation ratio of Cu nanoparticle is remarkably higher than that of Cu microparticle. Moreover, nanoparticles of CuO and Cu2O can be further transformed into cupric ion with transformation ratio over 90%. The high transformation ratio and the transformation mechanism of nanoparticles are discussed. (c) 2004 Elsevier Ltd. All rights reserved.
