Acta hydrochimica et hydrobiologica, 1993 AbstractDie Remobilisierung von Zink aus Flußsedimenten aus Neckar und Rhein mittels Nitrilotriessigsäure wird experimentell untersucht und als Desorption aufgefaßt. Das Gleichgewicht zwischen gelöstem und an Sediment fixiertem Zink wird mittels der Adsorptionsgleichungen von Freundlich, Langmuir sowie einem linearen Ansatz beschrieben.

Agricultural Water Management, 2017 Abstract Potassium (K) is an important nutrient for agricultural crop growth. Adsorption of K in soil involves fertilizer optima for enhancing crop productivity and efficient nutrient management. Adsorption is often necessary to predict K transport and losses, such as solid/liquid distribution in soil, plant uptake, and transportation with water and ...

Soil Research, 1981 Four adsorption equations were fitted to phosphate isotherm data for 38 soils from northern New South Wales. The two-surface Langmuir equation provided the best fit to the data. The Freundlich equation, however, was almost as effective, provided that an estimate of native adsorbed phosphate was included.

Journal of Environmental Science and Health, Part B, 1981 Freundlich K values cannot be directly converted from one set of units to another unless the slope, N, is unity. Dimensional analysis of the Freundlich equation shows the units of K to be moles(1-N) L(N)g-1, instead of the commonly used units, moles/g. A mathematical relationship exists between the ratio of K values in two different sets of units, and ...

RELATIONSHIPS BETWEEN CONSTANTS OF THE FREUNDLICH EQUATION AND TEMPERATURE FOR GASEOUS ADSORPTION
Chemical Engineering Communications, 1989Abstract For the Freundlich equation, the linear dependences of In k and n on T and In k on n were derived theoretically and examined by experimental data. In addition, the influence of the adsorbed amount on the isosteric heat of adsorption was also studied.

Adsorbent consumption advantages of a countercurrent two- and three-stage process are described. The Freundlich equation and equilibrium-stage were used to deduce these adsorption processes; it was proved that large adsorbent savings were obtained from operations of these systems in most cases.
