摘要：

This work examines the simultaneous removal of barium, chromium, manganese, and iron from produced water using microemulsion systems (Winsor II) in a one-step process. The Scheffe net experimental design was used to assess the effect of microemulsion composition in the removal efficiency. The optimum extraction point for the simultaneous removal of metals was composed by (w/w): 72 % aqueous phase (synthetic produced water), 9 % oil phase (n-hexane), and 19% cosurfactant/surfactant (butan-1-ol/saponified coconut oil = 4); reaching values above 94% for all studied metals, demonstrating the viability of the developed methodology for the correct management of metals from produced water.
