R. Boussenadji et al., DETERMINATION OF PHENYLUREA HERBICIDES IN WATER USING MICROCOLUMN HIGH-PERFORMANCE LIQUID-CHROMATOGRAPHY WITH UV AND ELECTROCHEMICAL DETECTION, LC GC, 11(6), 1993, pp. 450
Low-nanogram levels of phenylurea herbicides in water con be easily de
termined using microcolumn high performance liquid chromatography with
UV and electrochemical detection. This article describes the analysis
of five commonly used herbicides in water at levels as low as 0.1 ppb
