Nicotinium dichromate - induced electron transfer in pentaamminecobalt (III) complexes of ∝-hydroxy acids in micellar medium
نویسنده
چکیده
Nicotinium dichromate (NDC) oxidation of pentaamminecobalt (III) complexes of ∝ hydroxy acids in micellar medium yielding nearly 100% of keto acid complex is ultimate product. The decrease in UV-Visible absorbance at 502 nm for Co(III) complex corresponds to nearly 0% reduction of the initial absorbance. The stoichiometry of unbound ligand and cobalt(III) complex is accounting for no reduction at the cobalt(III) centre. The kinetic and stoichiometric results have been accounted by a suitable mechanism.

متن کاملSimultaneous Spectrophotometric Determination of Iron, Cobalt and Copper by Partial Least-Squares Calibration Method in Micellar Medium
Iron, cobalt and copper are metals, which appear together in many real samples, both natural and artificial. Recently a classical univariate micellar colorimetric method has been developed for determination of these metal ions. The organized molecular assemblies such as micelles are used in spectroscopic measurements due to their possible effects on the systems of interest. The ability of mi...

H-Point Standard Addition Method (HPSAM) was applied for the simultaneous determination of V(V) and Fe(III). The method is based on the complex formation of V(V) and Fe(III) with chromazurol S (CAS) in acidic media and in the presence of cetyltrimethylammonium bromide (CTAB) as a micellizing agent. Acidic media and the presence of a micellar system improve selectivity and sensitivity. Fe (I...
