Electrochemical sensor based on Pt-Au nanoparticles-decorated 3D reduced graphene-modified screen-printed electrode for simultaneous determination of herbicides isoproturon and diuron in agricultural products

Key Points

• Simultaneous determination of isoproturon and diuron shows effective detection capabilities.
• Detection limits for the method reach 1.0 μg/L for both herbicides, providing a sensitive approach.
• Electrochemical analysis employs a screen-printed electrode modified with platinum-gold nanoparticles for enhanced performance.
• This method highlights the need for efficient herbicide monitoring in agricultural practices to ensure safety.
