Three kinds of aluminas with different pore structures, synthesized using different methods, were investigated for the removal of Cr(VI) by batch adsorption tests. And commercial alumina was investigated to compare the removal efficiency. To understand the adsorption process, kinetics studies were performed and the results showed that the kinetics rate was fitted well by the pseudo-2nd-order kinetic...
In this study, mesoporous alumina materials were constructed by using GP-1/PG organogel or agarose hydrogel respectively as a template. The XRD, SEM and TEM characterizations were performed to determine the crystalline phase and microstructure of the alumina. Our results suggest that different mesostructures could be formed using different gel systems. The alumina synthesized in GP-1/propylene glycol...
