摘要：
The highly dispersed water pools have been shown to be ideal nanostructured reaction media, or microreactors, for preparing ultrafine particles used in catalytic processes, coatings, medical preparations and semiconductors. Copper sulfate particles were prepared at room temperature by precipitation from AOT (sodium bis(2-ethylhexyl)sulfosuccinate) microemulsions. The effects of pH, the concentration of aqueous copper salt, the ratio of water over surfactant concentrations (w(o)=:[H2O]/[AOT]), the time of precipitation on the particle formation and stability have been investigated. The shape and size of copper sulfate particles were analyzed by means of video enhanced microscopy, absorption spectroscopy and turbidimetry.
