Abstract:
The study includs the preparation and charazchtion of three new compounds of the schiff bases are : | 1- L1 is prepared from the condensation of 4-amino antipyrine with Penzaal acetone . | 4,4'-((1Z,1'E)-(1-phenylbutdiylidene)bis(azanylylidene))bis (1,5-dimethyl-2-phenyl-1Hpyrazol-(2H)-one)3 | 2- L2 is prepared from the condensation of4-amino antipyrine with Asetayl acetone | 4,4'-((1Z,1'E)-pentane-2,4-diylidenebis(azanylylidene))bis(1,5-dimethyl-2-phenyl-1H-pyrazol-3(2H)- one | 3- L3 is prepared from the condensation 4-amino antipyrine with Slsldehid as a first step then it is is reactance output with 3.4-di amino toluene . | 2,2'-((1Z,1'E)-( (3E,3'E)-3,3'((4-methyl-1,2-phenylene)bis(azanylylidene)) bis(1,5-dimethyl-2-phenyl-2,3-dihydro-1H-pyrazole-4-yl-3- ylidene))bis(azanylyidene))bis(methanylylidene))diphenol | The ligands were characterized by using Elemental Analysis (C.H.N), Infrared Spectroscopy (FT-IR) ,Uv-visible Spectroscopy , Nuclear Magnetic Resonance Spectroscopy (1H-NMR) , Mass Spectra . It is appeared that prepearing ligands are tetra chelatingagents kind (N2O2) for the ligands L1 and L2 and kind (N4) for the ligand L3. The complexed are prepeared from reaction the prepearing ligands with some transitional elements (Ni+2 , Co+2 , Cu+2) and the ligends and their complexes were characterized by methods of spectral analysis,Uv-visible Spectroscopy,Infrared Spectroscopy (FT-IR) , Mass Spectra and the Molar Electrical Conductivity .And from the result that we know the complexes are octahedral and their general formula [M(L) Cl2] , whereas M = Ni+2 , Co+2, Cu+2 . The study includs an extraction of nickel(II) ion from its aqueous solutions using solvent extraction technique by employing the reagent L3. The optimum extraction conditions are studied to obtain a better distribution ratio of values for (D) to reach the best percent extrected (%E) to extract nickel (II) ion . It is noted that the best values of distribution ratio (D) and the best percent extrected (% E) extracting nickel ion duo with the reagent L3 at the time of shake (15) minutes .The best extraction to nickel(II) ion with reagent L3 at temperature (25C°). As it turns out from this study that the best acidic function nickel(II) ion extraction in the aqueous phase with reagent L3 in the organic phase | when the (PH=9),also the study shows that the best values of distribution ratio (D) and the percent extrected (% E) for nickel(II) ion extraction when its constriction was (120 μg/ml) | (4.5×10-4 M ).The reagent L3 concentration (1× 10-4 M) . Chloroform was the best organic solvent for an extraction process for nickel(II) ion with reagent L3.The reagent L3 also is used for extraction Ni+2 from water of the Euphrates River City of Nasiriyah and the distribution ratio (D) =4.81 and the precent of extrected =%82 as it becomes out the reagent has high efficiency for extrected from the sample .
