Tricalcium Phosphate Anhydrous Powder typically contains 300 to 400 mg/Kg (w/w) of aluminum. This level can be determined utilizing AAS and standard based on known standards. In this study, we have determined the amount of aluminum metal present in sample of Tricalcium Phosphate Anhydrous Powder using Atomic Absorption Spectrophotometer (AAS). The method has high precision and accuracy. The results of aluminum determinations obtained by employment of N2O-C2H2 flame AAS methods. Great care is necessary for preparation of the blank. The need to subtract blank with standard calibration curve this was done automatically. The accuracy was checked with recovery test of aluminum added to the sample before analysis. With employment of AAS method 98.5% and 99.0% of added aluminum was recovered. The detection limit for the determination of Al was 0.5 mg/Kg and results meet the requirements.
