A novel purification method for copper sulfate using ethanol
This work presents a method for the purification of technical-grade copper sulfate by precipitation with ethanol. We demonstrate a selective separation to the desired purity level, leaving impurities in solution. The effects of altering the volume ratio of ethanol to copper sulfate solution, the solution pH, and the initial concentration of ...
