摘要

An effective adsorbent called mesoporous aluminosilica pellets (MAP) was developed to remove Hg(II) from fluid media such as drinking water. Scanning Electron Microscopy (SEM), transmission electron microscopy (TEM), energy dispersive X-beam spectroscopy (EDX), Fourier Transform Infrared Spectroscopy (FTIR) and Brunauer-Emmett-Teller (BET) examined the surface characteristics of the MAP. The stability time for Hg(II) is 6 h and MAP seems 8.3 mg g− 1 sorption capacity at pH 6.5. The pseudo-first-order model gave a good fitting (R2:0.988) showing the physisorption of Hg(II) take-up. The Sips model has the top fit to the Hg (II) sorption data indicating that the sorption on the surface of MAP happens in the interaction sites disseminated heterogeneously. The physisorption process is confirmed by the exothermic Hg(II) uptake. HCl revealed the best eluent for Hg(II) ions desorption and was used to determine adsorbent reusability more than 10th sorption/desorption cycles.
