| Résumé : | Trace amounts of molybdenum catalyze the reduction of selenium (IV) to the element by tin (II) in hydrochloric acid medium. The absorbance of the red colloidal selenium is read at 390 nm. Potential interferences are avoided by separating the molybdenum by solvent extraction. Physiological concentrations of molybdenum are determined in 10 ml. of ashed human blood or plasma and 1 ml. of ashed human urine. © 1979, Taylor & Francis Group, LLC. All rights reserved. |
