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....

| Summary: | 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 (III) and V (V) could be determined simultaneously in the range of 0.1-2 and 0.2-2 µg / mL, respectively, and with the ratio 1:20 to 10:1 Fe(III)/V(V) in the mixed samples. The proposed method was successfully applied to the simultaneous determination of Fe(III) and V(V) in tap, river, saliva and plasma samples. |
