Aqueous glyphosate (GLYP) was voltammetrically detected using a Cu‐(poly)pyrrole composite electrochemically deposited on activated carbon fiber for the first time in a single‐step method. Differential pulse voltammetry indicated good linearity (R² = 0.9902) in the response over 0.02–12 mg L⁻¹ range, with a low limit of detection (0.01 mg L⁻¹). The sensor exhibited reproducibility for soil and fruit samples (RSD values = 2.41 and 3.87%, respectively). The response showed repeatability over 100 consecutive measurements. The response was also unaffected by the interfering substances containing the same functional groups as in GLYP and its metabolite. The method described in this study is facile.

伏安法检测铜和聚吡咯电改性活性炭纤维上的草甘膦水溶液

草甘膦水溶液（GLYP）是使用单步方法首次电化学沉积在活性炭纤维上的Cu-（聚）吡咯复合材料进行伏安法检测的。差分脉冲伏安法表明，在0.02–12 mg L ^-1范围内的响应中线性良好（R ² = 0.9902），检出限较低（0.01 mg L ^-1）。该传感器对土壤和水果样品均具有再现性（RSD值分别为2.41和3.87％）。该响应在100次连续测量中显示出可重复性。该反应也不受包含与GLYP及其代谢物中相同官能团的干扰物质的影响。在这项研究中描述的方法很容易。
