Synthesis of hybrid materials and application to the retention of some effluents
Abstract
Abstract This present work is subdivided into two main parts: the first part consists in preparing the adsorbent: the double-layered hydroxide Mg/AL-CO3, which was prepared according to the co-precipitation method described by MIYATA and then grafting this LDH with Taurinyl-phosphonic acid (TPA) by anion exchange. The new synthesized material Mg/Al-TPA is applied to the retention of mercuric ions Hg+2. The characterization of this product was carried out by different methods such as Fourier transform infrared (FTIR), x-ray diffraction (DRX) and Brunauer–Emmett–Teller (BET) to explain the physical adsorption. In the second part, the material obtained was studied for the retention of Hg+2 ions and gave an extraction yield of 73% , with 0.1\xa0g of adsorbent at pH\xa0=\xa05.8 and T\xa0=\xa025° C for a grafted LDH.
