Auteurs : RBID : ISTEX:216_1989_Article_BF00483568.pdfAbstract
The polymeric chromogenic reagent PV · FPAQ has been synthesized by condensing 7-(4-formylphenylazo)-8-quinolinol (FPAQ) with poly(vinyl alcohol) (PVA). With indium(III) the reagent forms in weakly acidic media a water-soluble yellow complex, whose absorption maximum is at 445 nm. The molar absorptivity of the complex was found to be 3.16×104 l · mol−1 · cm−1 and Sandell's sensitivity 3.6 ng · cm−2. Beer's law is obeyed over the range 0–30 μg of indium(III) per 25 ml of solution. A Spectrophotometric method for the determination of indium has been worked out and applied to synthetic and authentic samples with satisfactory results.
