Flow injection-photoinduced-chemiluminescence determination of ziram and zineb

A simple, sensitive and rapid method for the determination of the pesticides ziram and zineb was described. This new method was based on the coupling of FIA methodology and direct chemiluminescent detection; this approach had not been used up to now with these pesticides. The additional use of an &a...

This new method was based on the coupling of FIA methodology and direct chemiluminescent detection; this approach had not been used up to now with these pesticides.

An additional 3-fold improvement in the analytical signal was also achieved by using quinine as sensitizer. The obtained throughputs were very high (121 and 101 h(-1) for ziram and zineb, respectively); this feature together with its low limit of detection (1 ngmL(-1)) makes this method particularly well suited to routine analyses of environmental samples.
