Sažetak
A new method for the extraction and spectrophotometric
determination of vanadium(V) using N-hydroxy-N-p-chlorophenyl-
N'-(3-chloro-4-methyl)phenyl-p-toluamidine(HCPCMPTA) in the
presence of phenols is proposed. The complexes, which can be
quantitatively extracted into chloroform, show J. max at 595-625
nm having a molar absorptivity in the range 6000-7600 1 mole-1
cm-1• Many ions commonly associated with vanadium(V) such as
Fe3+, Cu2+, Ti4+, Zr4+, W6+, Mo6+, Mn2+, Nb5+ and Ta5+ do not interfere.
The method has been applied for the determination of vanadium
in standard steel samples.
