Spectrophotometric determination of oxalate ion with N,N'-diethyl-N,N'-[[4,4'-dihydroxy-1,1'-binaphthalene]-3,3'-diyl]bisbenzamide and copper(II).
A simple and rapid spectrophotometric method for the determination of oxalate ion was established by the fading of a colored complex between N,N'-diethyl-N,N'-[[4,4'-dihydroxy-1,1'-binaphthalene]-3,3'-diyl]bisbenzamide and copper(II). Beer's law was obeyed in the concentration range of 0.1 - 2.0 microg cm(-3) for oxalate ion, with an effective molar absorptivity at 533 nm and the relative stand...
متن کاملIndirect spectrophotometric determination of some catecholamine drugs
Catecholamine drugs are aromatic vic-diols in which both the 3or 4-position is unsubstituted and these positions are not sterically blocked. Epinephrine(EP) or adrenaline(I) and norepinephrine(NE) or noradrenaline (II) are catecholamine drugs that are widely used in the treatment of allergic emergencies, status asthmatics, bronchial asthma, ventricular bradycardia, cardiac arrest, glaucoma, and...
متن کاملSpectrophotometric Determination of N-Acetyl-L-Cysteine and N-(2-Mercaptopropionyl)-Glycine in Pharmaceutical Preparations
A simple spectrophotometric method for the determination of N-acetyl-L-cysteine (NAC) and N-(2-mercaptopropionyl)glycine (MPG) in pharmaceutical preparations was developed, validated, and used. The proposed equilibrium method is based on a coupled two-step redox and complexation reaction. In the first step, Fe(III) is reduced to Fe(II) by NAC or MPG. Subsequently, Fe(II) is complexed with 2,4,6...
متن کاملInteraction of silver(I) ions with N,N,N’,N’-tetrakis- (2-hydroxypropyl)-ethylenediamine (Quadrol)
N,N,N’,N’-tetrakis-(2-hydroxypropyl)-ethylenediamine (Sche me 1), which is also known as Quadrol (Q), due to its perfect chelating properties with regard to copper(II) ions is widely used as a ligand in electroless copper plating solutions [1–6]. Therefore, analysis of literature sources on the interaction of metal ions with Quadrol shows that the majority of publications deal with copper(II). ...
متن کاملSpectrophotometric determination of Pb(II), Fe(III) and Bi(III) in complexes with 1,2-diaminocyclohexane-N,N,N',N'-tetraacetic acid (DACT).
A UV spectrophotometric method was developed for simultaneous determination of ions: Pb(II), Fe(III) and Bi(III) in complexes with DACT. Zero-order and derivative spectra were used for the determinations. Under the established experimental conditions the described method furnished reliable results with low limit of detection (from 0.09 microg x mL(-1) to 1.75 microg x mL(-1)), high recovery (fr...
