Modifications to the Freundlich equation to describe anion sorption over a large range and to describe competition between pairs of ions

open access: greenEuropean Journal of Soil Science, 2005
Summary We measured sorption of selenite and phosphate, both separately and in competition, in a Chilean Andisol. We also used previously published data for competitive sorption of arsenate and phosphate by a clay subsoil. We wrote computer programs that allowed us to compare the fits of differing versions of equations to describe ...

KINETIC FREUNDLICH EQUATION APPLIED TO SOILS WITH A HIGH RESIDUAL PHOSPHORUS CONTENT

open access: closedSoil Science, 1998
For soils with low plant-available phosphorous (P) content, the kinetics ofP sorption can be described adequately using the kinetic Freundlich equation (Q = at m C n ), where a, m, and n are fitting parameters. When this equation is used for soils that already contain a large amount of plant-available P as a result ofprevious P additions, the problem ...

Effectiveness of Activated Carbon from Jackfruit Skin for The Heavy Metal Lead (Pb) Adsorption Using The Langmuir and Freundlich Equations

open access: diamondEquilibrium Journal of Chemical Engineering
<p><span lang="EN-US"><strong>ABSTRACT. </strong>Activated carbon is a commonly used medium for adsorption to combat environmental pollution in both water and air. It is produced from plant or plantation waste containing carbon. Jackfruit skin, often considered as plantation waste, contains lignocellulosic compounds and has the ...

Evaluation of phosphate sorption capacity and external phosphorus requirement of some agricultural soils of the southwestern Ethiopian highlands

open access: yesSains Tanah: Journal of Soil Science and Agroclimatology, 2021
One of the most soil fertility management problems for crop production on acidic soils of the Ethiopian highlands is phosphorus fixation. The research was executed to assess the P-sorption capacity and to determine the external P requirement of different

SILICON BEHAVIOR IN SOILS CONTAINED DIFFERENT SILICON AND PHOSPHORUS CONCENTRATIONS USING ADSORPTION MODELS [ [PDF]

open access: yesArab Universities Journal of Agricultural Sciences, 2018
Silicon (Si) is an element, not essential, but is beneficial for some plants. The Freundlich model was used to describe Si adsorption on soil samples incubated with different Si and phosphorus (P) concentrations.

The Removal of Atrazine and Benalaxyl by the Fly Ash Released from Kosovo A Power Plant

open access: yesInternational Journal of Analytical Chemistry, 2022
The development of low-cost adsorbent coal FA (Kosovo A) for pesticide removal is an important area of scientific research. With this study, we show the potential of adsorption of coal FA (Kosovo A) for the removal of benalaxyl and atrazine from water ...
