| Abstract: | Different effects of divalent metal ions on electrochemiluminescence (ECL) sensor with Ru(bpy)32+ immobilized in Eastman‐AQ membrane were investigated. Mg2+, Ca2+ and Fe2+ can elevate the ECL of Ru(bpy)32+/proline; while metal ions that underwent redox reactions on the electrode such as Mn2+ and Co2+ presented intensive quenching effects on Ru(bpy)32+ ECL. Also, the quenching effect of Mn2+ on the ECL sensor with Ru(bpy)32+ immobilized in Eastman‐AQ membrane enhanced to about 30‐folds compared with the case that Ru(bpy)32+ was dissolved in phosphate buffer, and the enhanced quenching effects of Mn2+ were studied. |
