Present study demonstrates the construction of a new electrochemical sensor by electropolymerization of safranine on the surface of modified nano NiO carbon paste electrode. Cyclic and differential pulse voltammetric techniques were applied for the detection of rutin using 0.1 M phosphate buffer solution (pH 5.5) as supporting electrolyte. Specific variables including solution pH, analyte concentration and scan rates were optimized to validate the method. The peak currents were proportional with rutin concentration between 1.61x10 −8 M to 2.30x10 −7 M. The assessed limit of detection and limit of quantification values were found to be 0.54x10 -8 M and 1.61x10
