Bone ash - Wikipedia

Bone ash is a white material produced by the calcination of bones. Typical bone ash consists of about 55.82% calcium oxide, 42.39% phosphorus pentoxide, and 1.79% water. The exact composition of these compounds varies depending upon the type of bones being used, but generally the formula for bone ash is: Ca5(OH)(PO4)3. Bone ash usually has a density around 3.10 g/mL and a melting point of 1670 °C (3038 °F). Most bones retain their cellular structure through calcination.

Studies on the chemical composition of bone ash.

Using a modification of Gabriel's method for the extraction of bones with a 3 per cent. solution of potassium hydroxide in glycerol, the author has prepared samples of bone ash from the vertebrae of a variety of animals from fishes to mammals. On these samples determinations have been made of calcium, magnesium, potassium, phosphate and carbonate.

Separation of actinides from a bone ash matrix with ...

12/06/1998  A method based on extraction chromatography for the separation of actinides from bone ash has been developed and tested. Group separation of Th, U, Pu and Am from the sample matrix, and, e.g. Sr, was done with a TRU Resin ® column. The sequential separation of the actinides was performed with UTEVA Resin ® and TRU Resin ® columns. The mean recoveries for the bone ash analyses

Sample sizes needed to detect a 2% difference in bone ash were calculated using the method of Zar. The addition of 6,000 FTU/kg increased tibia ash from 26 to 37%, 29 to 41%, and 33 to 43% on Days 7, 14 and 21, respectively (method B). With bones from 7-d-old chicks, the same number of samples was necessary to detect a 2% difference using methods A and B. With bones from 14- and 21-d-old ...

A simple analytical method was developed for the determination of 90 Sr in fish bone ash samples. The adsorption behaviors of 26 metal ions on Sr Resin and AnaLig Sr-01 resin were examined. The obtained distribution coefficients show that Sr Resin has suitable selectivity. The proposed method consists of co-precipitation with calcium phosphate and purification by Sr Resin.

A complete conversion of bovine bone ash to HA can furnish as much as 1 kg of HA from 1.6 kg of compact bone [1]. This extracted HA contains valuable trace ions, which play a crucial role in the bone re-generation process and are known to speed up the bone formation process. Incorpora-tion of one or more trace ions into the synthetic HA is a laborious process and as a result ion-substituted HA ...

Cupellation - Wikipedia

Cupellation is a refining process in metallurgy where ores or alloyed metals are treated under very high temperatures and have controlled operations to separate noble metals, like gold and silver, from base metals, like lead, copper, zinc, arsenic, antimony, or bismuth, present in the ore. The process is based on the principle that precious metals do not oxidise or react chemically, unlike the ...
