Abstract:
BACKGROUND/NEED:
Through our batch tests, we found that this technique will be effectively applied for arsenic removal from groundwater. However, it is needed to conduct experimental works with a real groundwater contaminated arsenic species in order to design the POU/POE application of arsenic removal.
OBJECTIVES:
The objectives of this study were as follows: (1) to develop novel adsorbents through synthesizing highly ordered mesoporous silica SBA-15 and incorporating lanthanum oxide using an incipient-wetness impregnation technique; (2) to characterize the physicochemical properties of these media using several fine characterization techniques such as; XRD, N2 gas isotherm analysis, and FTIR; (3) to evaluate the adsorption capacities through performing adsorption kinetics and isotherms of arsenate; and finally (4) to try to elucidate the adsorption behavior of the media in connection with the physicochemical characterization discovered by above fine tools.
