Figure 1. XRD and FTIR analyses from the HA/Alg composite. (a) Peaks are noted due to HA crystallinity pattern, in accordance with the standard sheet PCPDFWIN 09.0432. (b) Intense and large water bands are observed at 3430 and 1646 cm-1 regions. On 1462 to 1414 cm-1 region, carbonate ions characteristic bands were found. On 1038, 961, 602 and 560 cm-1 regions, phosphate ions characteristic bands were found. Hydroxyl ions bands were observed at 3570 and 635 cm-1 regions.
