Thermal Characterization and Lifetime Estimation of the Humus Lombricospt
(Scientific Research, 2014-01)
Through this study, the humus produced in the breeding place of Universidad Autonoma de Occidente was thermally characterized. The humus was submitted to a heating program controlled by the Differential Scanning Calorimetry ...
Equilibrium adsorption of proteins
(1970)
The adsorption of bovine serum albumin (BSA) at an air/water interface was shown to be reversible and the equilibrium adsorption isotherm measured for concentrations between 0.001% and 10.0%. The desorption of BSA into a ...
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 ...
Electrochemical method to study the environmental behavior of Glyphosate on volcanic soils: Proposal of adsorption-desorption and transport mechanisms
(Elsevier B.V., 2019)
Glyphosate is used extensively worldwide, but current evidence suggests detrimental effects on the environment, pollinators, and human health. Glyphosate adsorption kinetics and adsorption/desorption were studied through ...
Effect of adding ZrM (M=Fe, Ni) intermetallic compounds on the hydrogen absorption/desorption properties of TiCr1.1V0.9 alloy
(Países Bajos, 2022-04-10)
Abstract
In this paper, the effect of intermetallic compounds Zr2Fe and Zr7Ni10 on the microstructure and first hydrogenation kinetic of TiCr1.1V0.9 alloy is reported. Samples were synthesized by arc melting separately ...
Effect of iEucalyptus globullus/i biochar addition on the availability of phosphorus in acidic soil
(Universidad Nacional de Colombia - Sede Bogotá - Facultad de Ciencias Agrarias, 2017-01-01)
Phosphorus (P) is one of the primary nutrients limiting crop production. The application of phosphate fertilizers in acidic soils leads to the formation of secondary insoluble compounds that reduces the effectiveness of ...
Determination of pesticides in river water using rotating disk sorptive extraction and gas chromatography-mass spectrometry
(Elsevier B.V., 2011)
The rotating disk sorptive extraction (RDSE) technique was applied to the determination of pesticides in aqueous samples. Pesticides of different polarities were considered in this study: chlorpyrifos, diazinon, fenvalarate, ...
Rotating disk sorptive extraction of triclosan and methyl-triclosan from water samples
(Springer, 2013)
A method of sample preparation based on use of
rotating disk sorptive extraction (RDSE) has been developed
for determination of triclosan (TCS) and methyltriclosan
(MTCS) in water samples. The sorptive and
desorptive ...
Mathematical modeling of the sorption isotherms of three varieties of industrial cassavaModelamiento Matemático de las isotermas de sorción de tres variedades de yuca industrial
(17th LACCEI International Multi-Conference for Engineering, Education, and Technology, 2020)
A high throughput approach to rotating-disk sorptive extraction (RDSE) using laminar cork for the simultaneous determination of multiclass organic micro-pollutants in aqueous sample by GC-MS
(Elsevier, 2020)
In this study, a high throughput approach to rotating-disk sorptive extraction (RDSE) using laminar cork as extraction phase is demonstrated for the first time in the determination of 20 multiclass organic micro-pollutants ...
