Spectrophotometric Study of Complex Formations between Alprazolam and Some Transition Metal Ions in Non Aqueous Solution
In this study, the complexation reaction between Alprazolam (ALP) and metal ions (Zn2+, Ni2+, Cu2+ and Co2+) was investigated by using spectrophotometry in ethanol solvent. The stoichiometry of M+/ALP complexes was calculated by applying the Job, molar ratio and Continuous Changes methods and the relevant diagrams were plotted for each metal ions in each method. The results show that the obtain...
متن کاملComplex formation of carnosine with purine nucleotides in aqueous solution.
This 1H-NMR study provides experimental evidence for an intermolecular interaction between the dipeptide carnosine (beta-alanyl-L-histidine) and the purine nucleoside 5'-monophosphates 5'-AMP, 5'-GMP. From the observed upfield shifts of the purine nucleotide and imidazole proton resonances it is concluded that the interaction is of the stacking type and that it involves the purine base of the n...
متن کاملMercury(II) penicillamine complex formation in alkaline aqueous solution.
The complex formation between mercury(II) and penicillamine (H(2)Pen = 3,3'-dimethyl cysteine) in alkaline aqueous solutions (pH approximately 2) has been investigated with extended X-ray absorption fine structure (EXAFS) and 199Hg NMR spectroscopy. By varying the penicillamine concentration (C(H(2)Pen) = 0.2-1.25 M) in approximately 0.1 M Hg(II) solutions, two coexisting major species [Hg(Pen)...
متن کاملCadmium(II) N-acetylcysteine complex formation in aqueous solution.
The complex formation between Cd(II) ions and N-acetylcysteine (H(2)NAC) in aqueous solution was investigated using Cd K- and L(3)-edge X-ray absorption and (113)Cd NMR spectroscopic techniques. Two series of 0.1 M Cd(II) solutions with the total N-acetylcysteine concentration c(H2NAC) varied between 0.2-2 M were studied at pH 7.5 and 11.0, respectively. At pH = 11 a novel mononuclear [Cd(NAC)(...
متن کاملPhotocatalytic Degradation of Safranin Dye from Aqueous Solution Using Nickel Nanoparticles Synthesized by Plant Leaves
In this paper, a facile and eco-friendly method for the preparation of Ni nanoparticles (Ni NPs) has been described based on the bioreduction of aqueous Ni(II) precursors with Phlomis cancellata Bunge extract. UV-visible spectrum of the aqueous medium containing Ni nanoparticles showed a peak of 390 nm. Since the experimental conditions of this procedure play vital roles in the synthesis...
