Speciation of vanadium(IV) and vanadium(V) as EDTA complexes in Benfield solution applying UV/VIS detection
AN-U-072
pt_PT
<p>The Benfield Process is a well known procedure to remove H<sub>2</sub>S and CO<sub>2</sub> from petroleum and industrial gases. Vanadium pentoxide is added as a corrosion inhibitor and is most effective in a certain V(IV)/V(V) ratio. Therefore, speciation and determination of V(IV) and V(V) is important. This speciation is easily achieved on A Metrosep A Supp 5 - 50/4.0 column with EDTA as an eluent and UV/VIS detection at 282 nm.</p>
