Sažetak
A simple, selective and sensitive method for the extractive
spectrophotometric determination of vanadium(V) using N-p-chlorophenyl-
2-naphthohydroxamic acid (CP-2-NHA) is described. Vanadium(
V) is quantitatively extracted from 3-8.4 M HCl as a violet
complex with CP-2-NHA into chloroform. Beer's law is applicable
in the concentration range 34 and 224 fig of vanadium(V) per 25 ml
of chloroform extract. The Sandell sensitivity of the system is
0.0089 μg/cm2 at 530 nm. The method has been satisfactorily
employed for the determination of vanadium in steel.
The solid complex, VOCI (C11H11N02Cl)2, was prepared and
characterised by melting point, elemental analysis, visible and
infrared spectra.
