Chemiluminescence determination of carbofuran at trace levels in lettuce and waters by flow-injection analysis.

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 ...
