Prediction of s-triazine components lipophilicity of total herbicides
A liquid chromatography method has been developed and validated for the determination of mathematical models for prediction of the lipophilicity of s-triazine compounds. Correlation between retention factors, RM 0 , of several s-triazine derivatives and their physico-chemical and structural properties has been studied by TLC on silica gel impregnated with paraffin oil. The research in this pape...
متن کاملPromotion of Sorghum Callus Growth by the s-Triazine Herbicides.
Growth-promoting action of simazine and other s-triazine herbicides was detected by the use of sorghum (Sorghum bicolor [L]. Moench) callus tissue and the chlorophyll retention test. Soil application of simazine [2-chloro-4, 6-bis(ethylamino)-s-triazine] at sublethal levels nearly doubled the growth-promoting action of sorghum root exudates. Treated plants yielded up to 26% more total protein t...
متن کاملDetermination of Seventeen s-Triazine Herbicides and Derivatives by High-pressure Liquid Chromatography
Mixtures of simazine, atrazine, ametryne, prometryne, deethylsimazine, deethylatrazine, hydroxysimazine, hydoxyatrazine, hydoxyprometryne, N-ethyland N-isopropylammeline, N-ethyland N-isopropylammelide, melamine, ammeline, ammelide, and cyanuric acid in aqueous solution were separated and determined in a single analysis with a detection limit of 30-400 pmol. The s-triazines were detected by a U...
متن کاملMeasured and Predicted Transport of Two S-triazine Herbicides through Soil Columns *
Effluent concentration of chloride and two pesticides (prometon and atrazine) were measured during column displacement experiments at two water flow rates. A constant suction of approximately 1300 Pa was maintained in the packed soil columns which were positioned vertically on top of a vacuum chamber enclosing an automatic fraction collector. Measured breakthrough curves (BTC’s) were analyzed i...
متن کاملOn the removal of s-triazine herbicides from waters using commercial low-cost granular carbons
The a dsorption capacities of three low-cost granular active carbons, used in a water treat ment fa cility for the re moval of the t riazine herbicid es propazine, pro metryn and pr ometon, wa s e valuated. Kin etic studie s showed that the three carbon sa mples used could be suitable in prac tice for the trea tment of moderate contents of the herbicides in contaminated waters. The apparent ads...
