Abstract
hydroxyapatite (HAP), a mineral adsorbent derived from the phosphate of Djebel Onk in Tebessa, Algeria. Initially, the HAP adsorbent was synthesized via the precipitation method employing natural phosphate. Subsequently, its structural properties were examined using X-ray diffraction (XRD) and Fourier-transform infrared spectroscopy (FTIR), confirming the successful synthesis of the HAP adsorbent. Finally, a response surface methodology (RSM) based on central composite design (CCD) was employed to investigate the effect of the adsorption parameters (i.e., initial
