Pulse amperograms (the currents flowing during cleaning step are removed from the amperograms) and corresponding calibration curves of rutin on unmodified (a), iron phthalocyanine modified (b) and ionic liquid modified (c) CPE. The potential was set to +600 mV for 60 s, current was sampled at this point. A 30 s cleaning step at –300 mV followed, during which aliquots of rutin sample solution were introduced into the measuring cell.
