Electrochemical sensor for picric acid by using molecularly imprinted polymer and reduced graphene oxide modified pencil graphite electrode

Here we report an electrochemical sensor for the determination of picric acid (PA) based on molecularly imprinted polymer (MIP) reduced graphene oxide (rGO) coated pencil graphite electrode (PGE). Pyrrole (Py) was electropolymerized surface rGO modified PGE, where PA used as template. After extraction molecules from matrix, MIP|rGO|PGE obtained. Computational studies were carried out to predict possible molecular interactions between template and polymer. The modifications characterized by various imaging techniques. shows linear response over concentration differential pulse voltammetric (DPV) analysis with good reproducibility. has significant mechanical stability detection limits 1.4 ?M. proposed applied quantify level present in soil water real analytical samples successfully.
