N2 - A sensor based on molecularly imprinted polymers (MIP) was
developed for determination of 3-(3,4-Dichlorophenyl)-1,1-
dimethylurea (diuron). The MIP were synthesized by free radical
polymerization in wich diuron acted as template, methacrylic acid
(MAA) acted as functional monomer and ethylene glycol
dimethacrylate (EGDMA) acted as crosslinker. For construction of
the sensor, glassy carbon electrode was modified with Nafion®
and MIP/NIP (non imprinted polymer) to see the contribution of
MIP, as a film, in the diuron recognition. Differential Pulse
Voltammetry was used to the quantification of diuron in a range of
response 0.4 - 1.2 V in a PBS (pH=8). All parameters affecting the
sensor were optimized. The sensor showed a linear response from
1.00x10-5 to 9.616x10-5 M in PBS 0.1 M (pH=8). The limit of
detection was 0.58x10-5 mol L-1. The nanostructured sensor was
prepared using carbon nanotubes and showed a 4 times greater
response than the glassy carbon, showing promising results.
