A novel electrochemical sensor for phosphorus determination in the high phosphorus liquid iron

open access: yesJournal of Materials Research and Technology, 2020
A novel phosphorus sensor based on the bilayer structure of ZrO2(MgO)/CaAl1.64O3.46 was fabricated and tested in high phosphorus liquid iron in this work, where the 4CaO∙P2O5 used as the auxiliary electrode was synthesized in situ by the CaAl1.64O3.46 ...

Organic and nutrient removal during start-up period for domestic sewage treatment by an A/O mixed carrier system [PDF]

open access: yesE3S Web of Conferences, 2020
This study combined biofilm method and A/O process reasonably to form the biological treatment system. This experiment focused on the performance of the system for domestic sewage according to the determination of CODCr, ammonia nitrogen, total nitrogen,

Determinants of phosphorus mobilization during hemodialysis [PDF]

open access: yesKidney International, 2013
Our recent work proposed a pseudo one-compartment model for describing intradialysis and postdialysis rebound kinetics of phosphorus. In this model, phosphorus is removed directly from a central distribution volume with the rate of phosphorus mobilization from a second, very large compartment proportional to the phosphorus mobilization clearance. Here,

Recipe Development for the Kidney Patient

open access: yesSaudi Journal of Kidney Diseases and Transplantation, 2021
Kidney patients are restricted from sodium, potassium, phosphorus, and protein. In thisstudy, new recipes have been developed in order to prevent the decrease in appetite, to control the loss of liquid electrolytes due to vomiting, to help patients feel ...

Effect of arsenic-phosphorus interaction on arsenic-induced oxidative stress in chickpea plants [PDF]

open access: yes, 2009
Arsenic-induced oxidative stress in chickpea was investigated under glasshouse conditions in response to application of arsenic and phosphorus. Three levels of arsenic (0, 30 and 60 mg kg−1) and four levels of P (50, 100, 200, and 400 mg kg−1) were ...

Quantitative determination of phosphorus in soybean lipids

open access: yesJournal of Lipid Research, 1969
Black and Hammond's method for determining lipid phosphorus has been modified for use with oils containing small amounts of phosphorus. The minimum amount of P that can be determined is 3 nmoles, with a coefficient of variation sd of 2%.

Phosphorus Metabolism of Mycobacteria: Determination of Phosphorus Compounds in some Mycobacteria [PDF]

open access: yesJournal of General Microbiology, 1956
SUMMARY: A procedure is described for the determinati on of phospholipid, ‘phosphoprotein’, ‘acid-soluble’ phosphate, pentosenucleic acid (DNA), deoxypentose-nucleic acid (DNA), and ‘insoluble’ polyphosphate in samples of mycobacteria of about 30 mg. dry weight.

Phosphorus determination in phosphoglycerides from thin-layer chromatograms

open access: yesJournal of Lipid Research, 1969
Phosphoglyceride phosphorus is readily determined directly on silica gel removed from thin-layer chromatograms, without elution, by a nondigestive procedure with a sulfuric-periodic acid reagent.
