Extraction of Copper Ions from Solution with Orform®
Description: Copper sulfate(aq) is added to the organic Orform® solution and shaken. The system is acidified, and the Copper ions migrate from the Orform® to the aqueous phase. With the addition of base, the copper ions migrate from the aqueous phase to the organic phase, which can be easily noted based on the color of the aqueous phase of the mixture. This process is used industrially for the separation of Cu ions from mineral phases during mining operations. This demo is a good example of industrial chemistry, organometallic chemical systems, phase separation and transition metal behaviors in solution. This demo features chelation, an important concept in biological and industrial purification chemistry. The organic solution is a product of the Chevron corporation.
