Abstract EN
High performance liquid chromatography (HPLC) system equipped with C18 reversed phase liquid chromatography column was used to determine vanadium in wet phosphoric acid and phosphate samples.
A rapid pre-column reaction of vanadium with 2-(5-bromo-2-pyridylazo)-5-diethylaminophenol was used without prior separation or adding any masking agents.
The chelate was detected after injected through the column by UV- Vis detector at wavelength 585 nm.
The molar absorptivity is 5.5 x104 and the retention time is 6.3 minutes.
The sensitivity of this reagent is twice as high as in the case of the use of (PAR) reagent.
The RSD was of the order 1.7 % for weak concentrations to 0.22% for high concentrations and.
The relative error (RE) was found to be between 3.21% and 1.07 %.
This method was found highly sensitive and selective and the results show a good accuracy and precision.-
