Dünnschichtchromatographische Bestimmung von Triazin‐Herbiziden in Wasser

Abstract
A description is given of the thin‐layer chromatographic determination of Triazine herbicides after the chloroform extraction and the detection with 0.1 N AgNO3 solution and irradiation by ultraviolet light. For simazine, Atrazine and Prometryne the detection limits are at 0.05 μg. Disturbances can be avoided if two different mobile solvents are used and preliminary cleaning by means of thin‐layer chromatography is done. The agreement of the Rf‐values in two different mobile solvents with the Rf‐values from known standard solutions is used as the criterion of identification.
