OXYGEN SENSING PROPERTIES OF A NEW RUTHENIUM-(II) COMPOUND

The design of efficient oxygen measuring devices has important environ mental, clinical and process control applications. Several methods are available for oxygen quantitation, but those based on the dynamic que nching of luminescence of inorganic compounds have several advantages. In this work the oxygen-quenching luminescence characteristics of a n ewly synthesized ruthenium (II) compound immobilized on an optical fib er was investigated using Stern-Volmer kinetic analysis. Results obtai ned show that the luminescence intensity of the newly synthesized comp ound exhibits a second order dependence on oxygen concentration from 0 -100 %. The oxygen sensing characteristics of this new compound are co mparable to other conventional oxygen sensing compounds.
