OPTIMIZATION OF PREPARATION CONDITION FOR HYDROXYAPATITE FROM CATFISH BONES

Abstract

Production of CFHAP at optimized experimental conditions of temperature and time was carried out using the central composite design (CCD) under response surface methodology (RSM). The temperature ranged from 300 Software, a total of thirteen (13) runs were used to design the experimental matrix of which the software specify. The resultant calcined mate while the adsorption capacity was determined by using a standard method, Methylene Blue Number method (MBN). The determined MBN was used to estimate the pore size. Catfish bone calcined at 300 °C for 1 h revealed the highest methylene blue number which is an indication of largest pore size. Characterization of the raw catfish bones and the run with the highest MBN (optimized CFHAP) was done to determine the morphology, functional groups, elemen and the pore volume using scanning electron spectroscopy (SEM), Fourier Transform Infrared spectroscopy (FTIR), Energy Dispersive Spectroscopy (EDS) and Brunauer area analyzer respectively at optimized condition from catfish bones at the temperature of 300 Abstract FJPAS Vol 2(1) ISSN: 2616 20 OPTIMIZATION OF PREPARATION CONDITION FOR HYDROXYAPATITE FROM CATFISH BONES Farombi, A.G 1 , Amuda O.S 2 and Alade A.O 3 Department of Science Laboratory Technology, Osun State Polytechnic, Iree, Nigeria.

Apatite is the name given to a group of crystals formula M10 (XO4)6 Y2. + , Pb 2+ , La 3+ and = PO4 3-, VO4 3-, , CO 2-and other various anions. Hydroxyapatite chemical formula Ca10 the apatite family. There are two types of hydroxyapatite, natural and synthetic hydroxyapatite.

The temperature ranged from 300 °C to 1000 °C and time from 1 to 2 h respectively. With this Design Expert Software, a total of thirteen (13) runs were used to design the experimental matrix of which the software specify. The resultant calcined material for each run was weighed to determin the adsorption capacity was determined by using a standard method, Methylene Blue Number method (MBN).
