Study on New Spectrophotometric Determination of Vanadium(V) with Chlorpromazine
摘要:
By using chlorpromazine as a new color reagent,spectrophotometric reactions with vanadium(Ⅴ) have been studied.In the medium of 0.25 mol·L-1 of H2SO4,chlorpromazine reacts with vanadium(Ⅴ) at room temperature to form a bright red complex,which exhibits a maximum absorption at 520 nm.Beer's law is obeyed in the concentration range of 0-2 μg and 2-40 μg V(Ⅴ)/10mL with molar absorptivities of 5.10×103 and 1.02×104L·mol-1·cm-1,respectively.
