Abstract

In this paper, separation, preconcentration and determination of Pb (II) as solvation species have been achieved by using methyl isobutyl ketone (MIBK) as an organic reagent. The spectrophotometric study of extracted solvation species shows that maximum absorption wavelength is 287nm. Accordingly, the experimental studies of extraction have optimum concentration of salting out KNO3 to form solvation species with higher extraction efficiency of 0.5M in the presence of 100µg of Pb+2 with 1×10-4 M from MIBK dissolved in chloroform and shaking the two layers for 10 minutes. Besides, this study involves thermodynamic and interferences investigations with application of spectrophotometric determination of Pb(II) in different environmental and vital samples.
