Webdrite to 659 cm-1 in bassanite indicates that the sulfate ions in bassanite are linked with water molecules by hydrogen bonding, because in general the hydrogen bonding will lower the frequency of the absorption band. In addition, there is a very weak peak at1003 cm-1 in gypsum, 1007 cm-1 in bassanite, and 1015 cm-1 in WebSulphate ions are the major source of sulphur which is considered an important element for sustenance of life as it is present in the essential amino and is required by cells to function properly. In this study we have successfully substituted sulphate ions (SO4−2) into hydroxyapatite (Ca10(PO4)6-x(SO4)xOH2-x) lattice via ion exchange process ...
