Simultaneous Spectrophotometric Determination of Vanadium(V) and Iron(III) in Micellar Medium by H-Point Standard Addition Method
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...

متن کاملSpectrophotometric determination of platinum metals. V.* Determination of palladium with Pyrogallol Red
A new spectrophotometric method for the determination of palladium with Pyrogallol Red is described. Its high sensitivity is dependent on the presence of micellar system of 1-carbethoxypentadecyltrimethylammonium bromide, which leads to the maximum colour formation in acid solutions (pH 5.5) in a shorter time interval than in the absence of tenside. The ternary pal ladium-dye-cation-active ten...
متن کاملEXTRACTIVE SPECTROPHOTOMETRIC DETERMINATION OF VANADIUM WITH ANTHRANILIC ACID IN PRESENCE OF PYRIDINE
Vanadium (III) gives a greenish- yellow complex with anthranilic acid in presence of pyridine. The complex is extractable with chloroform and is used for photometric determination of vanadium by measuring the absorbance at 390 nm against a reagent blank. Beer's Law holds good in the range of 1-20 pg V/ml. Moderate amounts of Pb (II) , Ca (II) , Sr (II) , Ba (II) , Cd (II) , Mg (II) , Mn (II...
