Apr 17, 2013 · Phosphorus content of bones (Fig. 6) and phosphate rock (Fig. 7) can be divided into two types of fractions based on the availability to plants (extraction with water and citrate) [22, 33].In the case first, the higher pool of phosphorus 94 %–not available to plant, and 6 %–available (2.8 % that dissolved in the water, and the remaining 3.2 dissolved in the citrate)

Portions of these preparations were reground to pass through successively smaller sieves, and subsequent analyses indicated the availability of phosphorus to be directly proportional to fineness of grind. A quantity of the citrate-insoluble fraction of the bone meal was obtained by following AOAC extraction procedures

what causes osteomalacia?

High levels of phosphorus cause the body to release more parathyroid hormone (PTH). This hormone is produced by the parathyroid glands housed in the neck area. It is responsible for the regulation of calcium levels in the blood. An increase in PTH can stimulate the extraction of calcium from the bones…

Jan 01, 2013 · Highlights Apatite and calcium phosphate compounds extraction from cod fish bones Bone calcination: biphasic material hydroxyapatite-calcium phosphate production Bone pre-treatments in solution change the material composition. Single phase materials (hydroxy-, chloro- or fluoroapatite) are obtained. Concentration of other elements (Na, F, Cl) suitable for biomedical applications

how to obtainred phosphorus| sciencing

Dec 15, 2018 · Red phosphorus, a relatively stable allotrope of phosphorus, has many uses. For example, it's a component of fireworks, flares and matches; it's used to dope silicon; and it's a plant fertilizer. You can obtain it by boiling urine with carbon or by reacting bone-ash with sulfuric acid and carbon

extraction of phosphorus,potassium, calcium, and

Nov 11, 2008 · A procedure for the simultaneous extraction of phosphorus, potassium, calcium and magnesium from soils, by an ion‐exchange resin procedure applicable to large‐scale advisory soil testing, is described. The important steps are the disaggregation of soil by shaking in water during 15 minutes with a glass marble, the transference of the

wo2014141021a1- method for recoveringphosphorusfrom

The invention provides a process for producing phosphate from an organic material, the method including the steps of (a) fermenting an organic material in a medium in the presence of at least one microorganism, wherein the fermenting is under conditions, and for a sufficient period of time, to produce a fermentation product; (b) treating the solids of the fermentation product with acid, in a

spectrophotometric determination of phosphate inmatrices

Jan 18, 2016 · The extraction schemes can be performed on fresh wet samples to avoid the exposure to air during drying. In that case, the porosity must be measured to calculate the mass of particles that were leached. Conclusion. Sequential extraction of phosphorus from natural solids is one of the geochemical tools used to study biogeochemical processes

The nutrition facts of commercial bone meal marketed as a calcium supplement gives us a general idea of the mineral content (900 mg calcium, 360 mg phosphorus, 9 mg magnesium per serving) of bone stock. That stuff comes from powdered “cattle raised in the United States,” which undoubtedly means corn-fed, nutritionally-deficient cows
