Polarographic behavior and determination of some <scp>S</scp>‐triazine herbicides

Abstract

Abstract The possibility for differential pulse polarography (DPP) determination of S ‐triazine has been shown and compared with gas‐chromatographic (GC) measurements. Good agreement was found between GC and DPP measurements in analyzing 20 samples of industrial wastewater. It was found, using controlled potential coulometry (CPC), that four electrons take part in electrochemical reduction steps. On the basis of this and polarographic measurements, the mechanism of electrochemical reduction of S ‐triazine was postulated.
