实验室硫酸铜制备的绿色化改进

Exploration on Green Preparation of Copper Sulfate in Laboratory

采用绿色环保的强氧化剂过氧化氢代替浓硝酸与铜粉和稀硫酸反应来制备五水合硫酸铜.用X射线衍射法、间接碘量法、重量分析法对所制得产物进行了表征.实验结果表明,此绿色制备方案无污染、操作简单便捷,制得的产品产率高、纯度好.

Hydrogen peroxide,a kind of green strong oxidant,is used to replace concentrated nitric acid to react with copper powder and dilute sulphuric acid to prepare blue copperas.The products are represented by X-ray diffraction techniques,indirect iodometry and gravimetric analysis.Results show that this experimental preparation method is free from pollution and its operation is convenient and fast.Products with high yield and purity can be obtained.
