The chemical compound hydroxyapatite preparation depending on the peel chicken eggs as a natural resource to be used medically


Abstract in English

In this research study of the conditions necessary for the preparation of a chemical compound hydroxyapatite HA [HA: Ca10 (PO4) 6 (OH) 2] Depending on normal vital source ( eggshell ) , which contains a large amount of calcium carbonate , which will be dealt with Acetic acid for acetate calcium Ca (CH3COO)2 , which in turn will be dealt with disodium hydrogen phosphate Na2HPO4, where and to prepare the treatment process depends on several factors , including: the concentration of the solutions , Solution temperature, stirring speed and addition , the degree of purity of the material used and its source, and the pH of the solution PH . The study showed that the chemical formula of the compound outlined in the bunting record is: Ca10 (PO4) 6 (OH) 2 and has a Molar ratio Ca / P stood at 1.65344 and preparation process was the best in the burned model of the form , dried and this was confirmed by sampling study of the two models , dried and burned in IR spectroscopy and spectroscopy x-ray diffraction XRD where the burned model output was crystalline either in the form of dried product was mixed crystalline and crystalline .
