Modeling Uranium Adsorption Using Hydroxyapatite Derived From Natural Phosphate Via Wet Precipitation Method

The main objective of this study is the recovery of uranium VI present in radioactive effluents through adsorption, using synthesis phosphate (SP) as an adsorbent. In the first phase, we developed (SP) through wet precipitation method. The (SP) was characterized using X-ray diffraction, scanning electron microscopy, infrared spectroscopy.  The second part of this work focused on the batch adsorption study of uranium VI by SP. We employed a numerical approach to analyze and optimize the parameters of the uranium VI adsorption process by SP, such as pH, adsorbent dose, and initial uranium VI concentration. The conclusions of this study indicated that the optimization was efficient to predict the uranium recovery by (SP) and the exploitation of abundant natural resources as sources of calcium and phosphorus has yielded significant results.
