 Abstract
The present paper brings forward the experimentally results regarding the copper extraction from low concentrated sulfate solution (<0,0157mol/l) by using the hollow fibers supported liquid membrane, impregnated with M5640 organic solvent (2-hidroxy-5-nonil-benzofenonoxima + organic ester modificator) diluted in kerosen.

 Rezumat
În lucrare se prezintă cercetările experimentale privind extractia cuprului din solutii apoase diluate de sulfat de cupru (<0,0157mol/l) folosind membrane lichide pe support solid de tip fibră tubulară, impregnate cu solventul organic M5640 (2-hidroxi-5-nonil-benzofenon oximă + modificator ester organic) diluat in kerosen.
