Spectrophotometric determination of some metal ions using azo dyes derived from chromium
Abdel Rahman Mohammed Ahmed Younes;
Abstract
The present work presents a study of the absorption spectra of the prepared chromone azo dyes under investigation in different organic solvents of various polarities as ethanol, 1-propanol, acetone, dioxane and dimethylformamide and the data are con-elated with the solvent parameters. The effects of the substitutions on the acid dissociation constant of the studied ligands were examined by spectral measurements. New spectrophotometric methods for the quantitative determination of some metal ions such as copper, zinc, vanadium, cobalt, molybdenum
Other data
