Abstract
The new organic reagent 2-[Benzo thiazolyl azo]-4,5-diphenyl imidazole was prepared and used as complexing agent for separation and spectrophotometric determination of Cu2+ ion in some samples include plants, soil, water and human blood serum. Initially determined all factors effect on extraction method and the results show optimum pH was (pHex=9), optimum concentration was 40?g/5mLCu2+ and optimum shaking time was (15min.), as well stoichiometry study appears the complex structure was 1:1 Cu2+: BTADPI. Interferences effect of cations were studied. Synergism effect shows MIBK gave increasing in distribution ratio (D). Organic solvent effect appears there is no any linear relation between dielectric constant for organic solvent used and distribution ration (D). Thermodynamically found the reaction was Endothermic reaction, with ?Hex= 0.0131 KJ.mole-1,?Gex=-54.20 KJ.mole-1 ,?Sex= 167.84 J.mole-1.Beer’s law was obeyed over the concentration 1-30?g/5mL, and ?=922.90 Lmol-1.cm-1,with detection limit 1.7×10-5and Sandell’s sensitivity 6.8× 10-7 gcm-2.
Highlights
Separation and determination of metal ions have been one of the most important topics of analytical Chemistry
New chelating resin was prepared by coupling Amberlite XAD-4 with 1amino-2-naphthole through an azo spacer
An extraction and sensitive differential pulse anodic stripping voltammetric method at hanging mercury drop electrode is described for the determination of Zn, Cu, Pb and Cd metal ions in water and 0.1MHCl extracts for Kakade, anise, Cumin, Caraway and black pepper [2]
Summary
The significant spectral overlap (Di)0.5 = 0.5667 which is about 75.3% overlapping of the UV/Vis, absorption spectra of Fe (II) and Cu(II) complexes necessitates chemometric assisted methods for simultaneous analysis of these ions in the pharmaceutical mixture. These metal ions have been analyzed simultaneously by UV/Vis. hydroxyquinoline was used as a chromogenic reagent. The reliability of the method was assured by analyzing the standard alloys, Brass, Bronze, and Phosphor-Bronze This method was successfully employed for the determination of Cu(II) in food and medicinal leafy samples and inter compared the experimental values using AAS and statistically evaluated using F-test.[7]
