PENAMBAHAN ASAM OLEAT TERHADAP Sistem transpor Cu(II) dengan zat pembawa oksin melalui teknik membran cair fasa ruah
TheÂ removalÂ ofÂ Cu(II)Â fromÂ aqueousÂ solutionsÂ hadÂ beenÂ employedÂ throughtÂ bulkÂ liquidÂ membraneÂ techniquesÂ withÂ arrangeÂ theÂ optimizationÂ conditionsÂ ofÂ transportÂ Cu(II)Â interfaceÂ system.Â TheÂ optimumÂ conditionsÂ ofÂ transportÂ wereÂ foundÂ toÂ beÂ 3.1510-4Â MÂ ofÂ Cu(II)Â atÂ pHÂ 3Â Â inÂ theÂ sourceÂ phase,Â Â 17.510-4Â MÂ oxineÂ dissolvedÂ intoÂ chloroformÂ asÂ membraneÂ phase,Â 0,15Â MÂ H2SO4Â asÂ acceptorÂ inÂ Â receivingÂ phase,Â stirringÂ rateÂ wasÂ 340Â rpmÂ andÂ Â itÂ wasÂ foundÂ thatÂ theÂ transportÂ ofÂ Cu(II)Â toÂ receivingÂ phaseÂ reachedÂ 97.41%Â duringÂ 6Â hours.Â TheÂ effectÂ ofÂ additionÂ Â oleatÂ acidÂ 1.57Â Â 10-3Â MÂ asÂ surfactantÂ Â inÂ membraneÂ phaseÂ resultedÂ aÂ rapidlyÂ timeÂ ofÂ Â transportÂ Cu(II)Â toÂ beÂ 3Â hours,Â whereinÂ Cu(II)Â transportedÂ Â intoÂ Â theÂ receiveÂ phaseÂ reachedÂ 97.83%Â Â andÂ remainedÂ Â inÂ feedÂ phaseÂ 0%.
