A simple, fast chemiluminescence (CL) flow-injection (FI) method based on the reaction of luminol with KMnO(4) in alkaline medium has been described for the direct determination of carbofuran. The method is based on the enhancing effect in the emission light from the oxidation of luminol produced in presence of carbofuran. The optimisation of instrumental and chemical variables influencing the CL response of the method has been carried out by applying experimental design, using the proposed flow-injection manifold. Under the optimal conditions, the CL intensity was linear for a carbofuran concentration over the range of 0.06-0.5mugml(-1), with a detection limit of 0.02mugml(-1). The method has been successfully applied to the determination of carbofuran residues in spiked water and lettuce samples.
