利用99%丙酮及95%酒精可以把硫酸銅晶體從實驗後的廢棄水溶液中取出來; 如同搾汁機一般,將硫酸銅結晶從水溶液中析出,其析出率可高達95.0%~90.0%。不需要外加能源,只需加入適量體積的丙酮、酒精溶劑靜置24小時不用攪拌,一顆顆漂亮的硫酸銅晶體就析出沉於底部。經過簡單的過濾及烘乾硫酸銅晶體就可以回收再利用,過濾的溶液經過簡易的蒸餾也可以回收丙酮及酒精,留在下次重複使用。如此便能解決化學實驗室硫酸銅廢液的儲存及處理。此種流程也可以用於,部分含有無機化合物的廢棄水溶液。簡易安全的操作,可回收再利用,減低衍生物的產生等,是綠色化學實驗的目標。By the use of 99% pure Acetone and 95% pure Alcohol can take the Copper Sulfate crystal out of the waste solution, as the way that juice press operates to separate the Copper Sulfate crystal from the solution. The rate or the separation can high up to 95.0%~90.0%.Without the need of extra energy, simply add proper mass of solvent like Acetone or Alcohol(refer to Result and Discussion) and place it 24 hours without stirring. Beautiful separated crystal can be recycled and ate capable to use again. By simple distillation, the filtered solution can recycle the added solvent such as Acetone or Alcohol which can also reuse next time. By doing so, the problem of storing and managing the waste solution of Copper Sulfate in laboratories of Chemistry will be solved. This procedure can also be used in parts of the waste solutions which contain inorganics. Simple and Sage operation, the capability of recycling and reusing and reducing derivatives etc., are the goals of Green Chemistry.
