Abstract
Distribution of Nickel (II) ions from aqueous media into solution of N,N’-ethylenebis (4-propionyl-2,4-dihydro-5-methyl-2-phenyl-3H-pyrazol-3-oneimine) (H2PrEtP) Schiff base in chloroform was studied. The synergistic effect of 4-propionyl-2,4-dihydro-5-methyl-2-phenyl-3H-pyrazol-3-one (HPrP) have been investigated and optimized. Various parameters for the extraction such as effect of pH of aqueous media, concentrations of the extractants (H2PrEtP and HPrP) and Nickel (II) ion were studied. Extraction with mixed ligands, H2PrEtP and HPrP was observed to have a pH½ of 5.75 with percentage extraction of 62.45 % corresponding to D value of 1.66 and logD value of 0.221. Optimum pH of 7.25 with percentage extraction of 99.14 % which corresponds to D value of 111.71 and logD value of 2.05 was also observed for the mixed ligand system. Extraction with single ligand, H2PrEtP was observed to be achievable at high pH values with pH½ of 7.75 corresponding to D value of 2.3935, logD value of 0.3790 and % E of 70.53 %. Optimum pH of 9.0 with D value of 107.83, logD value of 2.04 and % E of 99.08 % was also observed. The extraction of Ni2+ increased rapidly as the concentration of the ligand H2PrEtP increased from 2.5×10-3 M to 4.0×10-2 M and that of HPrP from 2.5×10-3 M to 2.5×10-2 M. Variation of the metal concentration was observed to have not much effect on the extraction hence the percentage extraction was high in all the metal concentrations studied.
