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).

Phosphorus is the eleventh most abundant element in the Earth's crust and is an essential element in DNA, RNA lipids, proteins, enzymes, energy carrier ATP, as well as an important factor in the development of teeth and bones. Phosphorus together with potassium and nitrogen are the three primary nutrients for plants (Tunnicliffe et al., 2014).

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. Agronomic studies were ...

I`ve been working on a way to obtain elemental Phosphorus. naturaly I`ll convert it to Red P4 rather than store it as White P4. so far the best way I can come up with is the conversion of Phosphoric acid with Carbon and distilling it. the starting chems I have, are …

Calcium Phosphate were extracted from dry old bones of animals through chemical treatment. The paper provided a brief summary of the experimental studies performed there in. showing the effects of two parameters in production rate. The raw material was analyzed for components by using x- ray fluorescence spectrometer.

Bones consist of organic (30%) and inorganic compounds (70%). Mineral parts of bones provide their stiffness and proper mechanical properties. The model compound corresponding to a mineral phase of bones is a nonstoichiometric hydroxyapatite (HAp), i.e. HAp whose molar ratio of calcium to phosphorus is different from 1.67. Biological apatites ...

The calcination temperature, calcination time, extraction method, and nature of bones are among the factors affecting the final properties of calcium phosphates such as Ca:P ratio, morphology, phase purity, size distribution and surface area. A general flow diagram of calcium phosphate extraction from fish bone is given in Fig. 4.

Heat-treated animal bone char (ABC) has not previously been evaluated for its potential as a phosphorus (P) fertilizer. ABC, Gafsa phosphate rock (GPR) and triple superphosphate fertilizer (TSP) were incubated in 12 soils. Dissolved-P was assessed by extraction with NaOH and bioavailability with the Olsen extractant. The rate of P dissolution from ABC was described almost equally well by the ...

A calcium-phospholipid-phosphate complex with a constant 1∶1 calcium to total phosphate molar ratio is shown to exist in rabbit and calf bone. This complex, which may be involved in the transport and depositon of bone mineral, appears to constitute a significantly greater proportion of the lipids of younger bone than of more mature bone. The complex was isolated by a modified Folch ...

White phosphorus explodes if it comes into contact with air. Transfer immersed white phosphorus into the airlock. When you do this, ensure that all air is forced out of the airlock to avoid an explosion. o 3 Move the immersed white phosphorus from the airlock into the airtight container. Do this without breaking the external airlock seal. o 4

The worldwide demand of phosphorus (P) is rising rapidly; however phosphate ores are not renewable. Fish bones contain high amounts of P, but hardly recycled or reused. Therefore, this study investigated P extraction from fish waste bones by acidic leaching method. The study shows that P content in fish bones ash is around 17 wt.%.

5. Phosphorus Extraction. Phosphorus is extracted from calcined bones, which have been heated to the red heat in contact with the air, so as completely to destroy the organic matter. This combustion can easily be made in a lime-kiln. This kiln is surmounted with a reverse cone, terminated by a pipe, more or less long, so that the gases can be ...
