摘要：
This work has been focused on the study of the viability of Barium removal, present in a waste liquid phase, by means of Non-Dispersive Extraction (NDE) in Hollow Fiber Modules. An organic solution based on DEPHA (Bis-2-ethylhexyl phosphate) 30% (v/v), Isopropilic Alcohol 30% (v/v) and Kerosene is used as selective extraction medium. For the extraction process was made a contactor with five hollow microporous propilenic fibers. A solution contained 100 ppm of BaCl2.H2O, level concentration very equal as generated on the petroleum industrial wastes, is used as liquid phase. A efficiency of 95,25% is obtained when the NDE take place at pH = 9, and them 9 hours of process.
