Solvent extraction of Pb(II) with AGDOMD
Journal Article
·
· Anal. Lett.; (United States)
The distribution of Pb(II) between an aqueous phase and a toluene phase containing dehydrated fatty acids found in distilled castor oil (AGDOMD) has been studied. Using the slope technique the conditional equilibrium constant of extraction was determined (kext = 1.02 x 10/sup -7/) and the main species present in the organic phase was identified as (PbNO/sub 3/R.2HR)/sub (o)/, where HR represents the fatty acid used.
