Ru(bpy)_3~(2+) Electrochemiluminescence Method for the Determination of Spermine

Based on the enhancement of spermine on Ru(bpy)2+3 electrochemiluminescence,a ECL method for the determination of spermine was established.This method was high sensitivity,wide linear range,and rapid analysis.Under the optimal conditions,a linear range of 5×10-8 ~5×10-5 mol/L was derived along with RSD values of 3.03% at 5×10-8 mol/L,and a detection limit of 2.31×10-8 mol/L was achieved.
