摘要

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 (R-2 = 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.
