Summary
Simple, direct, and sensitive low temperature phosphorimetric methods for the determination of monuron, diuron, and fenuron in EPA solvent are described. The minimum detectable amounts are 0.2, 0.1, and 0.02 p. p. m. for monuron, diuron, and fenuron respectively. The ranges in linearity of the analytical calibration graphs are 0.2–10, 0.1–7.5, and 0.1–20 p. p. m. for monuron, diuron, and fenuron respectively. The procedure for monuron has been applied to the analysis of a solid commercial formulation.
Zusammenfassung
Die Messung der Chemilumineszenz bei tiefer Temperatur ist ein einfaches, direktes und empfindliches Verfahren zur Bestimmung der Pestizide Monuron, Diuron und Fenuron in EPA-Lösung (Diethylether∶Isopentan∶ absol. Alkohol, 5∶2∶2). Die erfaßbaren Mindestmengen sind 0,2, 0,1 bzw. 0,02 ppm. Die Eichkurven sind zwischen 0,2 und 10, 0,1 und 7,5 bzw. zwischen 0,1 und 20 ppm geradlinig. Das Verfahren wurde zur Analyse von Monuron in einem festen Handelsprodukt verwendet.
