| Resumen en inglés | A low cost spectrophotometric cell for use in flow analysis was manufactured in acrylic and adapted to a commercial spectrophotometer. The application of this cell was performed in the determination of chromium (VI) in steel samples using the reaction with the alkaloid brucine in presence of oxalic acid and 0.6 mol L-1 sulfuric acid. The cell allows an enlarged analytical range, diminishing the extension of dilutions, which is useful for on-line monitoring of industrial processes |
