Abstract(s)
Microwave-assisted solvent extraction was combined with anodic adsorptive
stripping voltammetry at a gold microelectrode to extract and quantify
the herbicide atrazine in spiked soil samples. A systematic study of
the experimental parameters affecting the stripping response was
carried out by square-wave voltammetry. The voltammetric procedure
is based on controlled adsorptive accumulation of atrazine at the potential
of 0.35V (versus Ag/AgCl) in the presence of Britton–Robinson buffer
pH (2.0). The limit of detection obtained for a 30 sec collection time
was 4.3x10-7 mol L-1. Recovery experiments, at the 1µgg-1 level of spiking, gave good results for the global procedure, and the values
found were comparable to those obtained by HPLC.
