“…At both sites, the PiÁCaMg fraction dominated in the Pi pool, which could result from a high pH (6Á7) of these soils. Such a correlation is confirmed by the findings of many studies (Ivanoff et al 1998;Ann et al 2000;Schlichting et al 2002;Litaor et al 2004).…”

“…One of them is a modification by Reddy et al (1998) based on the Chang & Jackson method (1957). This sequential phosphorus fractioning method is widely used in American studies for soils in boggy areas (Ivanoff et al 1998;Reddy et al 1998;Ann et al 2000). Its scheme is presented in Fig.…”

“…One example of this is the use of vegetated filter strips, which have been proven effective for P removal (Serodes and Normand 1999;Jamieson 2000). In addition, the use of amendments that contain Ca, Fe, or Al could be used to bind P and enhance treatment efficiency and the P-holding capacity of the wetland system (Ann et al 2000).…”

. 2002. Phosphorus adsorption characteristics of a constructed wetland soil receiving dairy farm wastewater. Can. J. Soil Sci. 82: 97-104. Adsorption to soil has been identified as a key wastewater P removal mechanism in treatment wetlands. Batch incubation experiments were performed to measure the capacity of a constructed dairy farm wetland in Pictou County, Nova Scotia, to remove P from solution. The constructed wetland had been receiving wastewater since 1996. Non-linear regression analysis was performed using the Langmuir adsorption model to describe the P adsorption characteristics for the wetland soil under study. The Langmuir model was adequate in describing the P adsorption characteristics of the system studied. The P adsorption maxima found were approximately 925, 924, and 1600 mg P kg -1 soil, for the deep zone soil, shallow zone soil, and a background soil (not receiving wastewater), respectively. The P adsorption maxima for the deep zone and shallow zone soils were not significantly different (P > 0.05) from one another, but were significantly lower (P < 0.05) than the background soil. These data, together with information on wastewater inflow and P loading, were used to predict a lifespan of 8 yr for this wetland, relative to P removal.Key words: Phosphorus, wetlands, constructed, adsorption, Langmuir, saturation Jamieson, T. S., Stratton, G. W., Gordon, R. et Madani, A. 2002. Adsorption du phosphore par une terre humide artificielle recevant les eaux usées d'une exploitation laitière. Can. J. Soil Sci. 82: 97-104. Un des principaux moyens pour extraire le phosphore (P) des eaux usées dans le traitement des terres humides est l'adsorption par le sol. Les auteurs ont recouru à l'incubation en lot pour jauger la capacité d'une terre humide artificielle à retirer le P dissous. La terre humide en question accueille les eaux usées d'une exploitation laitière du comté de Pictou, en Nouvelle-Écosse, depuis 1996. On a appliqué l'analyse par régression non linéaire au modèle d'adsorption de Langmuir pour préciser les propriétés du sol à l'étude. Le modèle de Langmuir décrit bien le mécanisme d'adsorption du système examiné. La quantité maximale de P adsorbée s'établit respectivement autour de 925, de 924 et de 1 600 mg par kg de sol pour la couche profonde, la couche superficielle et le sol témoin (ne recevant pas les eaux usées). La quantité maximale de P adsorbée ne diffère pas sensiblement (P > 0,05) entre la couche profonde et la couche superficielle, mais elle varie sensiblement de celle relevée dans le sol témoin (P < 0,05). Selon ces résultats et d'après les données sur l'apport d'eaux usées et la charge de P, les chercheurs estiment que la terre humide à l'étude parviendra à saturation au bout de huit ans.

“…Adam et al, (2007) [3] reported that the shells and filtralite as natural materials were been tested for their phosphorus sorption capacity, both with batch and column experiments and found that the phosphorus removal rate of 92 and 91 was measured in the columns of shells and filtralite respectively, for the entire experimental period. It was reported that zeolite and pelleted clay, either alone orin combination with soils, alum, calcite and dolomite, was found to improve the phosphorus sorption capacity [4].…”

The removal of phosphorus from water using marble dust as sorbent material was studied by conducting batch tests, kinetic sorption model and isotherm model. The kinetic sorption model based on a pseudo equation was applied to predict the rate constant of sorption. Thorough investigations to understand the mechanism of phosphorus sorption onto the marble dust using kinetic sorption models, pseudo first order and pseudo second order kinetic sorption models showed that the kinetic sorption is consistent with the second order model, from which it can be inferred that the mechanism of sorption is chemisorption. The Langmuir and Freundlich isotherm models were applied to describe the equilibrium isotherms. The results of isotherm models showed that the Langmuir isotherm agrees very well with the experimental data compare with Freundlich isotherm. Batch tests and kinetic sorption models results showed that using the marble dust as sorbent material could be remove more than 94.3% of phosphorus from water.
