Qualitative and Quantitative Determination of Folic acid in Tablets by FTIR Spectroscopy

Qualitative and quantitative determination of chemicals especially that deal with drugs and pharmaceuticals can be considered as important issues in scientific research to insure human safety and security. With this direction of scientific research, folic acid had been determined qualitatively and quantitatively through applying FTIR technique. By applying a weight range of the pure compound, the obtained results showed several absorption peaks with standard curves that obeyed Lambert-Beer Law. Also, HPLC technique applied and compared with FTIR of different pharmaceuticals in local Iraqi market. The relative percentage error (E%) and Recovery percentage (Rec. %) results for both methods proved that sampling procedure in FTIR technique for both pure and pharmaceutical samples was more superiority beside simplicity.
