Flow Injection Spectrophotometric Determination of Fenoxaprop-p-ethyl Herbicide in Different Grain Samples after Derivatization
Propomos um método espectrofotométrico para a determinação do herbicida fenoxaprop-p-etil, usando injeção em fluxo.O fenoxaprop-p-etil foi convertido num ácido hidroxamico, na presença de hidroxilamina dihidrocloridrica em meio alcalino. O ácido hidroxâmico obtido reagiu com ferro(III) formando um complexo hidroxamato de ferro(III), vermelho. A absorbância do complexo foi medida a 500 nm em sis...
متن کاملEnvironmental Fate of Chiral Herbicide Fenoxaprop-ethyl in Water-Sediment Microcosms
The environmental fate of the herbicide fenoxaprop-ethyl (FE) in water, sediment and water-sediment microcosm was studied and degradation products fenoxaprop (FA), ethyl-2-(4-hydroxyphenoxy)propanoate (EHPP), 2-(4-hydroxyphenoxy)propanoic acid (HPPA) and 6-chloro-2,3-dihydrobenzoxazol-2-one (CDHB) were monitored. FE, FA, EHPP and HPPA were chiral and the environmental behavior was investigated ...
متن کاملSeed Alkaloids Content and Antioxidant Enzymes Activity in Black Henbane as Influenced by Ammonium Nitrate Application and Water Deficit Stress
Background: Since alkaloids are nitrogenous compounds, the availability of nitrogen (N) is expected to play an important role in the biosynthesis and accumulation of alkaloids in plants. Objective: This study intended to investigate the nitrogen (N) fertilization and water deficit stress (WDS) effects on seed tropane alkaloids elicitation including hyoscyamine (HYO) and scopolamine (SCO), and ...
متن کاملAnalysis of Structure-Activity Relationships of auxin – like molecules
Auxins have been the first plant growth regulators discovered several decades ago. They play a complex and important role in the dendritic network of the physiological processes in plants. Nevertheless, a correlation between their chemical structure and its biological implication could not be found. Many theories on correlations of structure and activity have been developed, which are based mai...
متن کاملAnticipatory pursuit is influenced by a concurrent timing task.
The ability to predict upcoming events is important to compensate for relatively long sensory-motor delays. When stimuli are temporally regular, their prediction depends on a representation of elapsed time. However, it is well known that the allocation of attention to the timing of an upcoming event alters this representation. The role of attention on the temporal processing component of predic...
