title: Nanoporous Copper Doped Aluminium Pillared Montmorillonite for Dye-containing Wastewater Treatment.
abstract: Copper doped aluminium pillared montmorillonite (Cu-Alpill-MMT) was prepared by adding Cu2+ into the suspension of aluminium pillared montmorillonite (Alpill-MMT) using high power ultrasonic treatment and calcining to CuO at 500 °C. The XRD and XRF data revealed that the doped CuO partially occupied both internal and external surfaces of the Alpill-MMT. The N2 adsorption/desorption analysis showed that the Cu-Alpill-MMT consisted of slit-like mesopores with two ranges of pore diameter, i.e. ~3.8 nm and ~6-30 nm. The Cu-Alpill-MMT exhibited the superior adsorption capacity for Basic Yellow 1 (BY1), however, it hardly adsorbed Reactive Orange 16 (RO16). The decolorization of RO16 was achieved when the H2O2 or H2O2/UV was introduced into the treatment system together with the Cu-Alpill-MMT, acting as heterogeneous catalyst for Fenton or photo-Fenton oxidation processes, respectively. The Cu-Alpill-MMT could exhibit the antibacterial activity after intimate contact with Escherichia coli ATCC®25922 under JIS L 1902: 1998 (Qualitative) test method.
