Photometric Determination of Ruthenium With 3-Nitroso-2,6-Pyridinediol
Chemistry and Biochemistry
Mathematics and Natural Sciences
A highly sensitive photometric method has been developed for the determination of ruthenium. The method is based on the purple colored complex formed when ruthenium is heated with 3-nitroso-2,6-pyridinediol (NPD) in slightly acidic solution. The molar absorptivity of the purple complex is 2.6 · 104l.mole−1,cm−1. The reaction ratio is 3∶1 reagent to ruthenium.
