Extraction of Traces of Copper as Tetra-Butylammonium Tetrathiocyanato Copper (II) and Its Spectrophotometric Determination Using Eriochrome Black T
An extraction-spectrophotometric method for the determination of traces of copper (II) is described. The method is based on the quantitative extraction of copper as tetrabutylammonium tetrathiocyanato copper (II) into methyl isobutyl ketone, followed by spectrophotometric determination, using eriochrome black T as a metallochromic indicator. The red-violet mixed complex of copper absorbs at...
متن کاملSpectrophotometric studies of copper (II) complexes of glycylglycine.
Spectrophotometric studies are presented of the glycylglytine-copper(I1) [GG-Cu(II)] system in aqueous solution under conditions in which the ligand is present in great excess (up to 1000: 1). In highly basic solution (pH 12 to 13) the spectral absorption maximum changes with increasing ligand concentration from 640 to 540 rnp. The spectral data are interpreted in terms of an equilibrium betwee...
متن کاملSpectrophotometric Determination of Copper(II) Using Diamine-Dioxime Derivative
A simple, rapid and sensitive spectrophotometric method is herewith proposed for the determination of copper(II) by using diamine-dioxime ligand, meso-3,6,6,9-tetramethyl-4,8-diazaundecane-2,10-dione dioxime or meso-HexaMethyl Propylene Amine Oxime (meso-HMPAO). This method is based on the formation of a stable 1 : 1 red-pink complex between copper(II) and meso-HMPAO in aqueous solution. Absorp...
متن کاملSimultaneous spectrophotometric determination of copper(II), lead(II) and cadrnium(II)
The full spectrum technique in the fourier domain was studied for simultaneous determination of Cu(II), Pb(II) and Cd(II) with 4-(2-pyridylazo) resorcinol (PAR). A program called SPGRFSQ. was designed to perform the calculations. Seven error functions were calculated for deducing the number of factors. Data reduction was performed using principal component analysis (PCA) algorithm. Experimental...
متن کاملSynthesis, Characterization and Crystal Structure Determination of Copper (II) Complexes with 2,2′-Dimethyl-4,4′-bithiazole
Copper(II) complex [Cu(dmbt)2(H2O)](ClO4)2 (1) was prepared from the reaction of copper(II) perchlorate hexahydrate with 2,2'-dimethyl-4,4'-bithiazole (dmbt) ligand in methanol at ambient temperature. The complex was quantitatively and qualitatively characterized by elemental analysis, absorption and infrared spectrometries. Complex [Cu(DMSO)5](ClO4)2 (2) was also synt...
