摘要:

A method has been developed for the selective determination of vanadium(IV) and vanadium(V) after interaction of VO3‐with plant roots. The separation of the two forms is possible, after dissolution in 1N HC1, by complexing selectively vanadium(IV) with cupferron and extracting the complex with CHC13. The quantitative determination of vanadium was carried out by direct current plasma (DCP) emission spectrometry.
