Sažetak
The spectrophotometric determination of vanadium(V) as a mixed thiocyanate-3-hydroxy-2-methyl-1-phenyl-4-pyridone (HX) complex and as a mixed thiocyanate-3-hydroxy-2-methyl-1-(4-tolyl)-4-pyridone (HY) complex is described. The extracted complexes in chloroform have a maximum absorbance at 450 and 650 nm. The optimal conditions for the extraction and spectrophotometric determination of vanadium(V) are determined. The solutions of the V-SCN-HX and V-SCN-HY complexes in chloroform obey Beer-s law in the range 1-10 ppm of vanadium, and are stable for at least 24 hr. The molar absorptivity of the method is 6.8x10(3) liters mol(-1) cm(-1). The molar ratio V : SCN : HX (HY) of the extracted complex is 1 : 1 : 2.
