The calibration curve for carbendazim detection presented good linearity in the concentration range of 0.50 to 15.0 mu M, with a sensitivity of 0.080 A/mol L-1 and a linearity of 0.998. The oxidation of fenamiphos on BDD electrode shows a dynamic range of concentration of 0.5 to 25.0 mu M and sensibility of 0.14 A/mol L-1. The recovery experiments showed values between 70 and 100% for spiked samples thus indicating the feasibility of the electroanalytical methodology to quantify CBZ and FNP in pure or natural waters.
