摘要：

A differential pulse voltammetric method for the determination of fenobucarb is proposed. This N-methylcarbamate pesticide is hydrolyzed in alkaline medium (0.02 M NaOH during ten min), and the resulting product 2 sec-butylphenol is oxidized at the glassy carbon electrode giving rise to a peak at a potential near 750 mV (pH 3.5). The linear relationship between I-p and fenobucarb concentration was established up to 1.00 x 10(-4) M concentration, the detection limit was 3.68 x 10(-6) M. The RSD is 3.74 % for a 1.0 x 10(-5) M concentration (n = 11, p = 0.05). The method has been satisfactorily applied to the analysis of water samples spiked with the pesticide.
