Determination of ultra trace amount Chromium in water samples with the 1-(2-PyridylAzo)-2-Naphthol, (PAN) by the bromate ion in sulfuric acid with kinetic spectrophotometric method
A new kinetic spectrophotometic method for the determination of trace amount Chromium (III) in Teareal samples has been described based on it s the catalytic effect on the oxidations of 1 - ( 2 –PyridylAzo ) - 2 - Naphthol, (PAN), by potassium bromated in sulfuric acid. The reaction is followedspec- trophotometrically by measuring the decrease in the absorbance at 469 nm. Under the optimumcondi...

متن کاملSimultaneous Determination of Traces of Lead and Cadmium in Various Samples by Differential Pulse Polarography after Adsorbing Their 1-(2-Pyridyazol)-2-Naphthol onto Microcrystalline Naphthalene
A highly selective, rapid and economical differential pulse polarographic method has been developed for the determination of trace amounts of cadmium and lead present together in various standard alloys and biological samples after adsorption of their 1-(2-pyridylazo)-2-naphthol complexes on microcrystalline naphthalene. Cadmium and lead complexes are equantitatively adsorbed on microcrysta...
