Static purification–concentration process: study of the system manganese, sulfuric acid–tri-n-octylamine
... point of view. For this doing we have developed a static liquid–liquid extraction technique associating extraction to re-extraction. A static purification–concentration process has been devised thanks to a liquid–liquid extraction–re-extraction reactor where the extraction compartment and th ...
