Solvent Extraction and Separation of Copper and Zinc from ...

Solvent extraction studies of copper and zinc have been carried out using Versatic 10 acid and Cyanex 272 separately from a model brass pickle liquor. Various parameters for the extraction and separation of copper and zinc such as effect of pH, extractant concentration, phase ratio etc. have been optimized. It was observed that copper was almost completely extracted into the organic phase ...

Solvent Extraction / FAQ | Radient Technologies

One of the goals of green chemistry is to prevent pollution at its source, as opposed to dealing with pollution after it has occurred. Radient's proprietary extraction technology allows for more efficient extraction of starting raw materials, lower temperature processing, the use of more benign solvents and lesser quantities of solvent and energy.
