1-Pentyl 4,6-Dihydroxy-5-Nitrosopyridine-3-Carboxylate: A New Reagent for the Determination of Osmium
Chemistry and Biochemistry
Mathematics and Natural Sciences
The reagent 1-pentyl 4,6-dihydroxy-5-nitrosopyridine-3-carboxy-late has been used to photometrically determine osmium. Several interferences are eliminated by an extraction prior to the development of the purple color formed between PDHNPC and osmium. This method is highly sensitive for osmium, the molar absorptivity for the complex being 3.4 × 104 at 550 nm. The reaction ratio is 1∶1 reagent to osmium.
