Abstract
AbstractThe present work reports for the first time the determination of paraquat (PQ2+) by Differential Pulse Adsorptive Stripping Voltammetry (DPAdSV) using a carbon paste electrode modified (CPME) with biochar obtained from castor oil cake at different temperatures (200–600 °C). The best voltammetric response was verified using biochar yielded at 400 °C (CPME‐BC400). Linear dynamic range (LDR) for PQ2+ concentrations between 3.0×10−8 and 1.0×10−6 mol L−1 and a limit of detection (LOD) of 7.5×10−9 mol L−1 were verified. The method was successfully applied for PQ2+ quantification in spiked samples of natural water and coconut water.
