摘要: Thin layer chromatography (TLC) densitometric method for simultaneous determination of seven chlorophenoxy and benzoic acid herbicides (2,4-D; 2,4,5-T; MCPA; 2,4-DP; MCPP; Dicamba MCPB) in water samples was developed validated. A mobile phase consisted benzene−dioxane−glacial acetic ratio 45: 10: 2 TLC silica gel 60 F254 aluminium plate were used. Detection carried out densitometrically at 280 nm. The linearity obtained the range 20–200 ng per band with correlation coefficient between peak area concentration each analyte higher than 0.9976. limits detection quantification 18 band, respectively. recoveries analyzed varied from 84.5 to 92.7%. can be used routine quality analysis natural surface ground samples.
