| סיכום: | The objective of this work was to determine the total phosphorus and the water-extractable phosphorus content of an incinerated bovine tibia bone sample without marrow. Regarding the extraction of total phosphorus, three acid digestions were compared, that is nitric acid and perchloric acid, hydrochloric acid and hydrogen peroxide, and hydrochloric acid. The bone sample was incinerated at 800 °C for 8 hours before the digestions in question. With respect to water-extractable phosphorus, two bone:water ratios were contrasted, that is 1:100 and 1:200. The total phosphorus per dry mass of the incinerated bone was 44,177 ± 0,810 % P2O5 (w/w DW), and the three acid digestions gave pragmatically similar values. The water-extractable phosphorus content per dry mass of the incinerated bone material was 0,013 ± 0,001 and 0,040 ± 0,001 %P2O5 (w/w DW) for the ratios 1:100 and 1:200, respectively. The higher fraction of phosphorus in the 1:200 ratio, despite being the most diluted alternative, could be the result of a lower impact of this on the pH of the extracting mix, which could have favored a greater movement of phosphorus to the water. If the benchmark is the content of water-extractable phosphorus in the ratio 1:200, then for every 100 g of total phosphorus contained in the incinerated bone sample, only 0.093 g of it is water-extractable phosphorus. |
