摘要：

The electrochemical behaviour of six triazine herbicides (atrazine, terbutylazine, desmetryne, prometryne, terbutryne and methoprotryne) was studied by fast scan differential pulse voltammetry (FSDPV) at a static mercury drop electrode and by constant potential coulometry. The adsorption of these compounds at the mercury electrode was employed for their determination by adsorptive stripping voltammetry (AdSV) in Britton-Robinson buffers. The detection limits calculated from regression analyses ranged between 0.1 and 0.9 mu g/l. Preconcentration (solid phase extraction on a C18 column) was used for the determination of very low contents in water samples. The recovery was 97-99.6%.
