Modeling the sorption kinetic of metsulfuron-methyl on Andisols and Ultisols volcanic ash-derived soils: Kinetics parameters and solute transport mechanisms
(2010)
Metsulfuron-methyl sorption kinetic was studied in Andisol and Ultisol soils in view of their distinctive physical and chemical properties: acidic pH and variable surface charge. Different kinetic models were applied to ...
Kinetics and mechanism of the reaction of a nitroxide radical (tempol) with a phenolic antioxidant
(2003)
In the absence of redox-active transition metal ions, the removal of Tempol by Trolox occurs by a simple bimolecular reaction that, most probably, involves a hydrogen transfer from phenol to nitroxide. The specific rate ...
Nicosulfuron sorption kinetics and sorption/desorption on volcanic ash-derived soils: poposal of sorption and transport mechanisms
(Elsevier, 2020)
Nicosulfuron sorption/desorption kinetics were studied through batch sorption studies in ten volcanic ash-derived Andisol and Ultisol soils with acidic pH and variable surface charge. Two different kinetic models were used ...
Mechanism and kinetics parameters of the reduction reaction of NO by CO on Pd/Al2O3 catalyst
(AMER CHEMICAL SOCIETY, 2007-05)
By means of a mechanism similar to that used by Peden and Permana for the reduction reaction of NO by
CO on Rh and the analytical solution of its kinetics equations, a set of kinetics parameters that interpret some
experimental ...
Oxidation of 3,5-ditert-butylcatechol catalyzed by copper(II) complexes. A kinetic study
(Elsevier Ltd, 1997)
Copper(II) complexes of the ligands (6-methyl-2,2′-dipyridyl)methane (MeDPM) and (6,6′-dimethyl-2,2′-dipyridyl)methane (diMeDPM) were prepared and used as catalysts for the oxidation of 3,5-ditert-butylcatechol to ...
Development of a Kinetic Spectrophotometric Method for the Determination of Ciclopirox Olamine in Pharmaceutical Sample
(Sociedad Chilena Química, 2016)
A simple and sensitive kinetic spectrophotometric method was developed for the determination of ciclopirox olamine in pharmaceutical formulations (cream). The method is based on the oxidation of ciclopirox olamine with ...
Self-similar singularities in the kinetics of condensation
(SPRINGER/PLENUM PUBLISHERS, 2006-11)
In this article, we review how a condensate builds-up infinite time, by a self-similar blow-up of the solution of three different models of kinetic equations. After the blow-up time, the growth of the coherent phase is ...
Lipid Metabolizing Enzyme Activities Modulated by Phospholipid Substrate Lateral Distribution
(2011)
Biological membranes contain many domains enriched in phospholipid lipids and there is not yet clear explanation about how these domains can control the activity of phospholipid metabolizing enzymes. Here we used the surface ...
Degradation kinetics of chlorpyrifos and diazinon in volcanic and non-volcanic soils: influence of cyclodextrins
(Springer Verlag, 2018)
© 2018, Springer-Verlag GmbH Germany, part of Springer Nature. The intensive use of insecticides such as chlorpyrifos (CPF) and diazinon (DZN) in the agricultural activities worldwide has produced contamination of soils ...
A kinetic study of the 1,3-dipolar cycloaddition reaction between N-p-methoxybenzyliden-α-phenylglycine methyl ester and nitrosobenzene
(1997)
The kinetics of the reaction between N-p-methoxybenzyliden-cc-phenylglycine methyl ester and nitrosobenzene, using benzene as the solvent and both acetic and chloroacetic acid as catalysts, was studied by means of UV-VIS ...
