| Summary: | The type of liquid membrane used in this work is the combination of bulk liquid membrane and emulsion liquid membrane operating in continuous mode. The existing method in of copper extraction such as solvent extraction, adsorption and chemical precipitation require additional step for removal and recovery of Cu(II). This drawback is overcome by using liquid membrane separation technique. The objective of this study is to remove and recover Cu(II) using liquid membrane. The feed phase is a real industrial wastewater that contain high amount of copper ions. The organic phase consist of waste cooking oil loaded with tributylphosphate (TBP) and di-2- ethylhexylphosphate (D2EHPA) and sulfuric acid as stripping phase. The parameter is feed flow rate at 3.79 L/hr, membrane flow rate at 2.73 1/hr and stripping phase at stagnant. The percent of extraction is evaluate at different reaction time and analyzed using inductive coupled plasma optical emission spectrometer (ICP-OES). The percent of extraction of Cu(II) is 44.22% at reaction time of 210 minute. |
