simultaneous voltammetric determination of acetaminophen and isoniazid by using magnetic nanocomposite modified screen printed graphite electrode

In this work, an electrochemical sensor based on a screen-printed graphite electrode (spge) modified with fe2moo4 magnetic nanocomposite was prepared for determination of acetaminophen (ac). the limit of detection (lod) of the method for ac was 0.05 μm and the sensor demonstrated a dynamic linear range from0.15–500.0 μm for analysis of ac. moreover, the fe2moo4/spge was used for the simultaneous determination of ac and isoniazid (inz). in co-existence system containing ac and inz, the developed sensor exhibited well-defined and separate dpv peaks (i.e., 630 mv) for these analytes.
