Adsorption and Desorption of Paraquat
The adsorption and desorption of paraquat (1, l'-dimethyl-4,4'-dipyridylium dichloride) in two tropical soils was determined under laboratory conditions. The two soils were taken from rice fields located in the North West of Perak state. The adsorption equilibrium time was 2 hours for both soil types. This adsorption equilibrium time was used to determine the effect of concentration on adsorpti...
متن کاملAdsorption/Desorption Kinetics of MoO4
The kinetics and mechanisms of molybdate adsorption/desorption at the g-Al2O3/water interface were studied by using the pressure-jump apparatus with conductivity detection at 298 K. A double relaxation was observed due to the adsorption/desorption process. Adsorption data and triple-layer model (TLM) simulation results suggest the formation of both monoand bidentate innersphere complexes (SMoO4...
متن کاملModeling Zn Adsorption and Desorption to Soils
The rate of reaction of trace metals between soils and solutions is important in predicting trace metal behavior as equilibrium may not be attained. Although chemical equilibrium models are commonly used for soil systems, there has been less progress in developing predictive kinetic models. Kinetics of Zn adsorption/desorption have been modeled based on the linear adsorption isotherm assumption...
متن کاملAdsorption–desorption of heavy metal ions
Adsorption and desorption studies on different types of adsorbents, including natural materials such as teak tree bark powder, rice husk, natural bentonite, different algae like Ecklonia maxima, Escherichia coli, Ascophyllum nodasum, Rhizopus nigricans, Cladophora fascicularis, goethite and soils of three nuclear power plant and artificial materials such as Fe oxide-coated sand, goethite pretre...
متن کاملIonic Adsorption and Desorption of CNT Nanoropes
A nanorope is comprised of several carbon nanotubes (CNTs) with different chiralities. A molecular dynamic model is built to investigate the ionic adsorption and desorption of the CNT nanoropes. The charge distribution on the nanorope is obtained by using a modified gradient method based on classical electrostatic theory. The electrostatic interactions among charged carbon atoms are calculated ...
