The immobilization of tris(2,2′‐bipyridyl)ruthenium(II), Ru(bpy) 3 2+ , at a glassy carbon electrode was achieved by entrapping the Ru(bpy) 3 2+ in a vapor deposited titania sol‐gel membrane. The electrogenerated chemiluminescence (ECL) of the immobilized Ru(bpy) 3 2+ was studied. The Ru(bpy) 3 2+ modified electrode showed a fast ECL response to both oxalate and proline. The ECL intensity was linearly related to concentrations of oxalate and proline over the ranges from 20 to 700 μmol L −1 and 20 to 600 μmol L −1 , respectively. The detection limits for oxalate and proline at 3σ were 5.0 μmol L −1 and 4.0 μmol L −1 , respectively. This electrode possessed good precision and stability for oxalate and proline determinations. The electrogenerated chemiluminescence mechanism of proline system was discussed. This work provided a new way for the immobilization of Ru(bpy) 3 2+ and the application of titania sol‐gel membrane in electrogenerated chemiluminescence.
