Once soil solution phosphorus (P) level optimum for plant growth is identified, P adsorption isotherms or their equations can further be used to estimate fertilizer P rates required to adjust this desired soil solution P level to obtain maximum yield. Surface soil samples were collected from a farmer's field area and research area.

Phosphate sorption by Greek alkaline soils evaluated with a modified Freundlich Equation
Zeitschrift für Pflanzenernährung und Bodenkunde, 1982AbstractPhosphate adsorption of calcareous and non calcareous alkaline Greek soils was studied using the Freundlich Equation modified as to take also into account q, the quantity of phosphorus (P) already existing in these soils. Relatively high amounts of phosphate added were adsorbed, with a minimum of 44.5% at the highest level of P addition, being ...

The effects of granules-inocula on the start-up of anaerobic reactors treating dairy manure were studied in a batch-fed reactor. The effects of start-up period and ratio of granules to feed were analyzed. Results indicated that the effects of start-up period could be described by Langmuir model, while the Extended Freundlich model could be used to ...

The Freundlich equation, X/m = K Ce N , is frequently used to express the partitioning of pesticides between solid (soil, sediment) and aqueous phases. When designing adsorption-desorption experiments, it would be useful to be able to estimate the equilibrium concentration, C e , in terms of the initial concentration, C e , if reasonable estimates of K

Abstract Studies on adsorption isotherms for 16 organic compounds such as benzene mono- or disubstitutes, fatty acids, and aliphatic alcohols in aqueous solutions on five commercial granular activated carbons were carried out at 25°C. It was elucidated that the Polanyi potential theory could only be applied to the adsorptions of sparingly soluble ...

Metal ion sorption plays a critical role in mitigating environmental pollution. However, there is a dearth of research data on the sorption characteristics of Cd2+ and Pb2+ ions on natural clay minerals in Akwa Ibom State, Nigeria. This study aims to investigate the sorption behaviour of Cd2+ and Pb2+ ions on natural clay minerals using the Langmuir ...
