hydroxyapatite nanoparticles
  In this study, hydroxyapatite nanoparticles (HAP), Ca5 (PO4)3(OH), were synthesized via wet-chemical precipitation methods. Physico-chemical properties of nanoparticles were characterized using high-resolution Transmission Electron Microscope (HR-TEM), X-ray Diffraction (XRD). The application of the synthesized adsorbent in clarification of mixed cane juice ”MJ”, were investigated via batch experiments in pilot scale. The effect of (HAP) on the behavior of dissolved non sugars ”calcium, silicate, and phosphate compounds”, compared with that effect of traditional sulfitation process were evaluated . The results show a significant difference in the removal of silica, 51.34% in the case of using hydroxyapatite nanoparticles, where as 36.25 % removal with traditional sulfitation method. And 38.3 % lowering in the remaining calcium content in the clarified juice CJ was achieved. Moreover, 16 ppm of P2O5 content in CJ after using hydroxyapatite nanoparticles, compared with 6 ppm P2O5 in the CJ resulted from traditional sulfitation process. These results mean a predicted soft scale formed in the evaporators, overcoming the hard to boiled massecuite ”HTB” phenomenon, and lower sugar losses in final molasses. The results were discussed via, physico-chemical properties of hydroxyapatite nanoparticles, that affect coagulation and flocculation of flocs formed.
