Uptake of Arsenic(V) with Aluminum Modified MCM-41

Abstract:

The highly ordered mesoporous MCM-41 was synthesized and modified with various content of aluminum (0-15%) using an incipient wetness impregnation technique. The prepared Al modified MCM-41 materials were characterized by XRD, and explored as adsorbents for arsenic(V) removal. Al loading and calcination temperature played significant roles in the absorbents structures and adsorption capacities. The maximal arsenic(V) adsorption capacity of 16.3 mgAs/gAl was obtained when Al loading of 10 wt% and calcination temperature of 400 °C were used.
