Characterizing phosphate desorption kinetics from soil : an approach to predicting plant available phosphorus
… reported as an effective way to characterize P desorption over a long-term in laboratoty studies. However, there is little information on the relationship between kinetics of P release using this new method and plant P uptake. This method consist of a procedure of shaking a sample for a long …

Field investigation and simulation of nutrient control in a fish-hatchery wastewater stabilization pond system
… system also had the greatest potential for P desorption from the sediments if the overlying P concentrations were to change. The secondary system is a polishing system with the majority of the flow but minimal P loading and removal. An iron and aluminum oxide based medium was characterized for …

Phosphate Reactivity in Long-Term Manure Amended Soils in the Ridge and Valley of Virginia
… (iii) inorganic speciation, and (iv) P desorption capacity of soils impacted over a long period of time by poultry litter (broiler and layer), dairy manure and commercial fertilizer applications. Soil chemical properties were measured with various extractions, while soil solution was …

Multi-reactional kinetic modeling of phosphate sorption on goethite using artificial neural networks
… which consists in assessing P sorption and desorption capacity of goethite at different temperatures and then investigating the kinetic mechanisms by applying multi-reactional modeling through Hopfield artificial neural network (HANN). Two mechanisms were investigated, a sequential reactions …

Ambient ionization - mass spectrometry: Advances toward intrasurgical cancer detection
… by analyzing sectioned or smeared tissue using desorption electrospray ionization (DESI). The physical form of the tissue, e.g. in vitro sampling, sectioned, or smeared, was inconsequential in differentiating normal from cancerous tissue; however, the spectra acquired by TS and DESI differed due …

ΚΙΝΗΤΙΚΗ ΤΗΣ ΕΚΡΟΦΗΣΕΩΣ ΦΩΣΦΟΡΟΥ ΑΠΟ ΤΕΣΣΕΡΑ ΕΛΛΗΝΙΚΑ ΕΔΑΦΗ. Η ΔΙΑΧΥΣΗ ΣΑΝ ΚΑΘΟΡΙΣΤΙΚΟ ΣΤΑΔΙΟ ΤΗΣ ΤΑΧΥΤΗΤΟΣ
THE KINETICS OF PHOSPHATE DESORPTION FROM THE SOLID PHASE OF THE SOIL IS OF CONSIDERABLE IMPORTANCE FROM BOTH THE AGRONOMIC AND ENVIRONMENTAL POINTS OF VIEW BUT PAPERS PUBLISHED ON THIS SUBJECT ARE BY FAR LESS NUMEROUS THAN THOSE RELATING TO THE THERMODYNAMICS OF THE PROCESS. THE PRESENT …
