Phosphorus (P) runoff from fields fertilized with swine (Sus scrofa domesticus) manure may contribute to eutrophication. The objective of this study was to evaluate the effect of aluminum sulfate (alum) and aluminum chloride applications to swine manure on P runoff from small plots cropped to tall fescue (Festuca arundinacea Shreb.). There were six treatments in this study: (i) unfertilized con...

background: the poisoning is mostly due to suicide and is observed in younger age groups. the systemic manifestations of alp poisoning are common but pernicious manifestations of them are cardiotoxicity, shock, and ards. the clinical hallmark of cardiotoxicity is arrhythmia. the aim of this study was to investigate cardiac arrhythmias in patients poisoned with alp who were admitted to razi hosp...

A new technique was accepted to fill the porosity of Al coating applied by arc thermal spray process to enhance corrosion resistance performance in artificial ocean water. The porosity is the inherent property of arc thermal spray coating process. In this study, applied coating was treated with different concentrations of ammonium phosphate mono basic (NH4H2PO4: AP) solution thereafter dried at...

Studies were conducted to compare the phosphate-binding efficacy of lanthanum carbonate directly with other clinically used phosphate binders and to evaluate any potential adverse pharmacology. To examine the phosphate-binding efficacy, rats with normal renal function and chronic renal failure received lanthanum carbonate, aluminum hydroxide, calcium carbonate, or sevelamer hydrochloride in sev...

An equilibrium model for the speciation of Al3+ in normal serum has been developed in which 81% of the aluminum is bound to transferrin. The remaining 19% exists primarily as Al(PO4)(OH)-, with minor amounts of citrate and hydroxide species. The model meets several key criteria. The concentration of free aluminum is below the upper limit set by the solubility product of aluminum phosphate. The ...

The advantages and drawbacks of existing wet chemical phosphorus (P) recovery technologies, their applicability to different types of sewage sludge ash (SSA) and the role of the decay products of detergent zeolites as a source of reactive Al in SSA are analyzed. Since neither a purely acidic nor a purely alkaline treatment are able to provide satisfactory technical solutions a wet chemical phos...

The use of spectroscopic techniques (especially phosphorus-31 nuclear magnetic resonance [(31)P-NMR] and X-ray absorption near edge structure spectroscopy) has recently advanced the analysis of the speciation of P in poultry litter (PL) and greatly enhanced our understanding of changes in P pools in PL that receive alum (aluminum sulfate) to reduce water-soluble P and control ammonia emissions ...

This article describes investigations on the phase development (T ≤ 1500℃) of phosphate-bonded Al2O3-MgAl2O4 high-temperature ceramics by a combination solid-state MAS NMR and X-ray diffraction analyses. The ceramic body was bonded with inorganic hydrogen orthophosphates (Al, Mg, Ca, Zr) total binder content 3 wt.% P2O5. binding mechanisms these could be extensively deduced analyses development...

a r t i c l e i n f o Keywords: ZnO nanoparticulates Phosphate Al activation Capacitor Electrochemical power sources We report on an innovative membrane-free aluminum/phosphate cell based on the activation of aluminum (Al) as anodic material using ZnO nanocrystal in phosphate rich electrolyte that is capable of generating sufficient power to power a light-emitting diode (LED), selected as a mod...

knowledge of the phosphorus (p) forms is essential for understanding the behavior of phosphorus. the aim of this study was to investigate the effect of wheat cultivation on different inorganic p forms of soil. a greenhouse factorial experiment in a completely randomized design was carried out with three replications in 20 soil types and plantation at two levels (with and without plantation). th...
