Effect of the nature and volume of the water-miscible
organic solvent
Different organic solvents such as THF,
acetone, ethanol, methanol and acetonitrile were tested
for the homogeneous liquid–liquid extraction. The
results show that in the presence of acetone, the
highest percent recovery for lead(II) is achieved in
addition to the formation of a proper oily drop. Thus,
acetone was selected for subsequent experiments.
