Sensitive Determination of Rutin Using a Nafion/PMB/Graphene Composite-Modified Glassy Electrode

A novel Nafion/PMB/G/GCE was prepared by firstly electro-polymerization of MB to G/GCE and then coating Nafion on PMB/G/GCE. The as-prepared modified electrode combining the advantages of Nafion, methylene blue and G was employed for the sensitive detection of rutin. The results showed that the peak current of rutin obtained on Nafion/PMB/G/GCE was obviously high compared to bare electrode and G/GCE. Under the optimized value of pH, which was pH 3.0, peak current of rutin had good linear relation with the scan rate. At the same time, peak current increased linearly with increasing concentration of rutin. The linear range was from 5×10-7 mol/L to 1.2×10-5 mol/L, and the detection limit was 9.5×10-8 mol/L

Title: Sensitive Determination of Rutin Using a Nafion/PMB/Graphene Composite-Modified Glassy Electrode

Description:

A novel Nafion/PMB/G/GCE was prepared by firstly electro-polymerization of MB to G/GCE and then coating Nafion on PMB/G/GCE.

The as-prepared modified electrode combining the advantages of Nafion, methylene blue and G was employed for the sensitive detection of rutin.

The results showed that the peak current of rutin obtained on Nafion/PMB/G/GCE was obviously high compared to bare electrode and G/GCE.

Under the optimized value of pH, which was pH 3.

0, peak current of rutin had good linear relation with the scan rate.

At the same time, peak current increased linearly with increasing concentration of rutin.

The linear range was from 5×10-7 mol/L to 1.

2×10-5 mol/L, and the detection limit was 9.

5×10-8 mol/L.
