Аннотация: A novel electroactive composite based on silicotungstic acid (SiW), poly-о-phenylene diamine (PPD) and reduced form of graphene oxide (RGO) was prepared by electrochemical synthesis on a planar screen printed carbon electrode (SPCE) coated with graphene oxide (GO). The new material was shown to have expressed electrocatalytic activity for the example of electrochemical behavior of the p-benzoquinone/hydroquinone redox couple on the RGO-PPD-SiW-modified electrode. Unlike most composites containing heteropolyacid anions, RGO-PPD-SiW demonstrates its properties not only in an acid but also in a neutral saline solution. The potential cycling in a saline solution retains some CVA peaks observed in 1 М H2SO4 environment. An addition of a local anesthetic of amide series (lidocaine, naropin, or chirocaine) to a saline solution was shown to change the CVA shape immediately. Upon washing the electrode with twice distilled water and filling with the initial saline solution or 1 М H2SO4, in each case the corresponding CVA curve returns to the original shape thus demonstrating the multiple usability of the composite electrode for analytical purposes by studying, for example, the presence of the said drugs in body fluids after administration.
