Electrochemical Studies of LbL Films With Dawson Type Heteropolyanion Glassy Carbon Electrode Sensor Modified for Methyl Parathion Detection

Rapid methyl parathion detection was measured using a fabricated glassy carbon electrode (GCE) sensor designed the layer-by-layer (LBL) method. Multilayer assemblies were developed on by alternating depositions of anions and cations in which Dawson Type Polyoxometalate ?-K 6 [(P 2 W 18 O 62 ·H O)]·14H (?P POM) polyethyleneimine (PEI) stabilized silver nanoparticles (?PEI-AgNPs) acted as cations, respectively. The redox behavior P POM within LBL assembly carried out via cyclic voltammetry. This thoroughly characterized UV-Visible, FT-IR, XRD, AFM, SEM techniques. fabricate GCE investigated for electrocatalytic activity to detect parathion. results clearly showed that successfully synthesized. More interestingly, current response detecting found be less than 1 ppm, proving this may exhibit potential applications targeted pesticide.
