abstract a large number of studies have shown that direct application of rock phosphate dose do not have enough efficiency to release phosphorus compared to chemical fertilizers. the main purpose of this study was to increase the efficiency of direct application of rock phosphate. incorporation of rock phosphate with sulfur, organic matter and inoculation with sulfur-oxidizing bacteria and phos...

Background: The role of phosphate hemostasis in development of thalassemia bone disease has not been extensively studied yet. Due to the lack of sufficient human studies about the changes of serum Fibroblast growth factor-23(FGF23) in patients with beta-thalassemia major as the first step of investigating the role of FGF23 in thalassemia bone disease, the present study aimed to investigate the ...

this experiment was lay out in order to evaluate the effects of different biofertilizers on seed yield, protein and oil of rapeseed in iran. the experiment was a factorial design with three replications. treatments were four nitrogen biofrtilizers (control (n1), nitroksin (n2), azotobacter (n3) and supernitroplat (n4)) and three phosphate biofrtilizers ( control(p1), biosfer phosphate (p2) and ...

Correction for 'The transformation from amorphous iron phosphate to sodium iron phosphate in sodium-ion batteries' by Yao Liu et al., Phys. Chem. Chem. Phys., 2015, 17, 22144-22151.

Iron (III) oxides are ubiquitous in near-surface soils and sediments and interact strongly with dissolved phosphates via sorption, co-precipitation, mineral transformation and redox-cycling reactions. Iron oxide phases are thus, an important reservoir for dissolved phosphate, and phosphate bound to iron oxides may reflect dissolved phosphate sources as well as carry a history of the biogeochemi...

The oxidation of either ferrous iron or sulfur by Thiobacillus ferrooxidans was selectively inhibited or controlled by various anions, inhibitors, and osmotic pressure. Iron oxidation was more sensitive than sulfur oxidation to inhibition by chloride, phosphate, and nitrate at low concentrations (below 0.1 M) and also to inhibition by azide and cyanide. Sulfur oxidation was more sensitive than ...

The effect of phosphate on adsorption and oxidation of catechol, 1,2-dihydroxybenzene, in a heterogeneous Fenton system was investigated. In situ attenuated total reflectance infrared spectroscopy (ATR-FTIR) was used to monitor the surface speciation at the nano-Fe3O4 catalyst surface. The presence of phosphate decreased the removal rate of catechol and the abatement of dissolved organic compou...

BACKGROUND High iron load might have a number of toxic effects in the organism. Recently intravenous (iv) iron has been proposed to induce elevation of fibroblast growth factor 23 (FGF23), hypophosphatemia and osteomalacia in iron deficient subjects. High levels of FGF23 are associated with increased mortality in the chronic kidney disease (CKD) population. CKD patients are often treated with i...
